  - 已解決 Linux 核心中的下列弱點：extcon: Modify extcon device to be created after driver data is set Currently, someone can invoke the sysfs such as state_show() intermittently before dev_set_drvdata() is done.

  - 已解決 Linux 核心中的下列弱點：tick/nohz: unexport __init-annotated tick_nohz_full_setup() EXPORT_SYMBOL and __init is a bad combination because the .init.text section is freed up after the initialization. Hence, modules cannot use symbols annotated __init. The access to a freed symbol may end up with kernel panic. modpost used to detect it, but it had been broken for a decade.
    Commit 28438794aba4 (modpost: fix section mismatch check for exported init/exit sections) fixed it so modpost started to warn it again, then this showed up: MODPOST vmlinux.symvers WARNING: modpost:

Initialize 'pi' instead to '&ata_dummy_port_info' to fix the possible kernel oops for good... Found by Linux Verification Center (linuxtesting.org) with the SVACE static analysis tool. (CVE-2022-49731)

  - 已解決 Linux 核心中的下列弱點：bridge: switchdev: Fix memory leaks when changing VLAN protocol The bridge driver can offload VLANs to the underlying hardware either via switchdev or the 8021q driver. When the former is used, the VLAN is marked in the bridge driver with the 'BR_VLFLAG_ADDED_BY_SWITCHDEV' private flag. To avoid the memory leaks mentioned in the cited commit, the bridge driver will try to delete a VLAN via the 8021q driver if the VLAN is not marked with the previously mentioned flag. When the VLAN protocol of the bridge changes, switchdev drivers are notified via the 'SWITCHDEV_ATTR_ID_BRIDGE_VLAN_PROTOCOL' attribute, but the 8021q driver is also called to add the existing VLANs with the new protocol and delete them with the old protocol. In case the VLANs were offloaded via switchdev, the above behavior is both redundant and buggy. Redundant because the VLANs are already programmed in hardware and drivers that support VLAN protocol change (currently only mlx5) change the protocol upon the switchdev attribute notification. Buggy because the 8021q driver is called despite these VLANs being marked with 'BR_VLFLAG_ADDED_BY_SWITCHDEV'. This leads to memory leaks [1] when the VLANs are deleted. Fix by not calling the 8021q driver for VLANs that were already programmed via switchdev.

AlmaLinux 9.2 ホストには、TuxCare ALMALINUX9.2:CLSA-2026:1783362244アドバイザリに記載されている複数の脆弱性の影響を受けるパッケージがインストールされています。

  - Linux カーネルでは、以下の脆弱性が解決されています: extcon: Modify extcon device to be created after driver data is set Currently, someone can invoke the sysfs such as state_show() intermittently before dev_set_drvdata() is done. And it can be a cause of kernel Oops because of edev is Null at that time. So modified the driver registration to after setting drviver data. - Oops's backtrace.

  - Linux カーネルでは、以下の脆弱性が解決されています: tick/nohz: unexport __init-annotated tick_nohz_full_setup() EXPORT_SYMBOL and __init is a bad combination because the .init.text section is freed up after the initialization. Hence, modules cannot use symbols annotated __init. The access to a freed symbol may end up with kernel panic. modpost used to detect it, but it had been broken for a decade.
    Commit 28438794aba4 (modpost: fix section mismatch check for exported init/exit sections) fixed it so modpost started to warn it again, then this showed up: MODPOST vmlinux.symvers WARNING: modpost:
    vmlinux.o(___ksymtab_gpl+tick_nohz_full_setup+0x0): Section mismatch in reference from the variable
    __ksymtab_tick_nohz_full_setup to the function .init.text:tick_nohz_full_setup() The symbol tick_nohz_full_setup is exported and annotated __init Fix this by removing the __init annotation of tick_nohz_full_setup or drop the export. Drop the export because tick_nohz_full_setup() is only called from the built-in code in kernel/sched/isolation.c. (CVE-2022-49675)

  - Linux カーネルでは、以下の脆弱性が解決されています: ata: libata-core: fix NULL pointer deref in ata_host_alloc_pinfo() In an unlikely (and probably wrong?) case that the 'ppi' parameter of ata_host_alloc_pinfo() points to an array starting with a NULL pointer, there's going to be a kernel oops as the 'pi' local variable won't get reassigned from the initial value of NULL. Initialize 'pi' instead to '&ata_dummy_port_info' to fix the possible kernel oops for good... Found by Linux Verification Center (linuxtesting.org) with the SVACE static analysis tool. (CVE-2022-49731)

  - Linux カーネルでは、以下の脆弱性が解決されています: bridge: switchdev: Fix memory leaks when changing VLAN protocol The bridge driver can offload VLANs to the underlying hardware either via switchdev or the 8021q driver. When the former is used, the VLAN is marked in the bridge driver with the 'BR_VLFLAG_ADDED_BY_SWITCHDEV' private flag. To avoid the memory leaks mentioned in the cited commit, the bridge driver will try to delete a VLAN via the 8021q driver if the VLAN is not marked with the previously mentioned flag. When the VLAN protocol of the bridge changes, switchdev drivers are notified via the 'SWITCHDEV_ATTR_ID_BRIDGE_VLAN_PROTOCOL' attribute, but the 8021q driver is also called to add the existing VLANs with the new protocol and delete them with the old protocol. In case the VLANs were offloaded via switchdev, the above behavior is both redundant and buggy. Redundant because the VLANs are already programmed in hardware and drivers that support VLAN protocol change (currently only mlx5) change the protocol upon the switchdev attribute notification. Buggy because the 8021q driver is called despite these VLANs being marked with 'BR_VLFLAG_ADDED_BY_SWITCHDEV'. This leads to memory leaks [1] when the VLANs are deleted. Fix by not calling the 8021q driver for VLANs that were already programmed via switchdev.

  - Linux カーネルでは、以下の脆弱性が解決されています: capabilities: fix potential memleak on error path from vfs_getxattr_alloc() In cap_inode_getsecurity(), we will use vfs_getxattr_alloc() to complete the memory allocation of tmpbuf, if we have completed the memory allocation of tmpbuf, but failed to call handler->get(...), there will be a memleak in below logic: |-- ret = (int)vfs_getxattr_alloc(mnt_userns, ...) | /* ^^^ alloc for tmpbuf */ |-- value = krealloc(*xattr_value, error + 1, flags) | /* ^^^ alloc memory */ |-- error = handler->get(handler, ...) | /* error! */ |--
    *xattr_value = value | /* xattr_value is &tmpbuf (memory leak!) */ So we will try to free(tmpbuf) after vfs_getxattr_alloc() fails to fix it. [PM: subject line and backtrace tweaks] (CVE-2022-49890)

  - USB: gadget: Fix use-after-free during usb config switch In the process of switching USB config from rndis     to other config, if the hardware does not support the ->pullup callback, or the hardware encounters a low     probability fault, both of them may cause the ->pullup callback to fail, which will then cause a system     panic (use after free).

The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1783362244 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: extcon: Modify extcon device to be     created after driver data is set Currently, someone can invoke the sysfs such as state_show()     intermittently before dev_set_drvdata() is done. And it can be a cause of kernel Oops because of edev is     Null at that time. So modified the driver registration to after setting drviver data. - Oops's backtrace.

  - In the Linux kernel, the following vulnerability has been resolved: tick/nohz: unexport __init-annotated     tick_nohz_full_setup() EXPORT_SYMBOL and __init is a bad combination because the .init.text section is     freed up after the initialization. Hence, modules cannot use symbols annotated __init. The access to a     freed symbol may end up with kernel panic. modpost used to detect it, but it had been broken for a decade.
    Commit 28438794aba4 (modpost: fix section mismatch check for exported init/exit sections) fixed it so     modpost started to warn it again, then this showed up: MODPOST vmlinux.symvers WARNING: modpost:
    vmlinux.o(___ksymtab_gpl+tick_nohz_full_setup+0x0): Section mismatch in reference from the variable
    __ksymtab_tick_nohz_full_setup to the function .init.text:tick_nohz_full_setup() The symbol     tick_nohz_full_setup is exported and annotated __init Fix this by removing the __init annotation of     tick_nohz_full_setup or drop the export. Drop the export because tick_nohz_full_setup() is only called     from the built-in code in kernel/sched/isolation.c. (CVE-2022-49675)

  - In the Linux kernel, the following vulnerability has been resolved: ata: libata-core: fix NULL pointer     deref in ata_host_alloc_pinfo() In an unlikely (and probably wrong?) case that the 'ppi' parameter of     ata_host_alloc_pinfo() points to an array starting with a NULL pointer, there's going to be a kernel oops     as the 'pi' local variable won't get reassigned from the initial value of NULL. Initialize 'pi' instead to     '&ata_dummy_port_info' to fix the possible kernel oops for good... Found by Linux Verification Center     (linuxtesting.org) with the SVACE static analysis tool. (CVE-2022-49731)

  - In the Linux kernel, the following vulnerability has been resolved: bridge: switchdev: Fix memory leaks     when changing VLAN protocol The bridge driver can offload VLANs to the underlying hardware either via     switchdev or the 8021q driver. When the former is used, the VLAN is marked in the bridge driver with the     'BR_VLFLAG_ADDED_BY_SWITCHDEV' private flag. To avoid the memory leaks mentioned in the cited commit, the     bridge driver will try to delete a VLAN via the 8021q driver if the VLAN is not marked with the previously     mentioned flag. When the VLAN protocol of the bridge changes, switchdev drivers are notified via the     'SWITCHDEV_ATTR_ID_BRIDGE_VLAN_PROTOCOL' attribute, but the 8021q driver is also called to add the     existing VLANs with the new protocol and delete them with the old protocol. In case the VLANs were     offloaded via switchdev, the above behavior is both redundant and buggy. Redundant because the VLANs are     already programmed in hardware and drivers that support VLAN protocol change (currently only mlx5) change     the protocol upon the switchdev attribute notification. Buggy because the 8021q driver is called despite     these VLANs being marked with 'BR_VLFLAG_ADDED_BY_SWITCHDEV'. This leads to memory leaks [1] when the     VLANs are deleted. Fix by not calling the 8021q driver for VLANs that were already programmed via     switchdev.

  - In the Linux kernel, the following vulnerability has been resolved: capabilities: fix potential memleak on     error path from vfs_getxattr_alloc() In cap_inode_getsecurity(), we will use vfs_getxattr_alloc() to     complete the memory allocation of tmpbuf, if we have completed the memory allocation of tmpbuf, but failed     to call handler->get(...), there will be a memleak in below logic: |-- ret =     (int)vfs_getxattr_alloc(mnt_userns, ...) | /* ^^^ alloc for tmpbuf */ |-- value = krealloc(*xattr_value,     error + 1, flags) | /* ^^^ alloc memory */ |-- error = handler->get(handler, ...) | /* error! */ |--
    *xattr_value = value | /* xattr_value is &tmpbuf (memory leak!) */ So we will try to free(tmpbuf) after     vfs_getxattr_alloc() fails to fix it. [PM: subject line and backtrace tweaks] (CVE-2022-49890)
