Rocky Linux 9.6 主机上存在安装的程序包，该程序包受到 TuxCare ALMALINUX9.6：CLSA-2026：1780052998公告中提及的多个漏洞的影响。

  - 已修复 Linux 内核中的下列漏洞：can: isotp: fix potential CAN frame reception race in isotp_rcv() When receiving a CAN frame the current code logic does not consider concurrently receiving processes which do not show up in real world usage. Ziyang Xuan writes: The following syz problem is one of the scenarios. so->rx.len is changed by isotp_rcv_ff() during isotp_rcv_cf(), so->rx.len equals 0 before alloc_skb() and equals 4096 after alloc_skb(). That will trigger skb_over_panic() in skb_put(). ======================================================= CPU: 1 PID:

    __netif_receive_skb+0x24/0x1b0 net/core/dev.c:5579 Therefore we make sure the state changes and data structures stay consistent at CAN frame reception time by adding a spin_lock in isotp_rcv(). This fixes the issue reported by syzkaller but does not affect real world operation. (CVE-2022-48830)

  - 已修复 Linux 内核中的下列漏洞：ceph: fix deadlock or deadcode of misusing dget() The lock order is incorrect between denty and its parent, we should always make sure that the parent get the lock first. But since this deadcode is never used and the parent dir will always be set from the callers, let's just remove it. (CVE-2023-52583)

  - 已修复 Linux 内核中的下列漏洞：trace_events_hist: add check for return value of 'create_hist_field' Function 'create_hist_field' is called recursively at trace_events_hist.c:1954 and can return NULL-value that's why we have to check it to avoid null pointer dereference. Found by Linux Verification Center (linuxtesting.org) with SVACE. (CVE-2023-53005)

  - 已修复 Linux 内核中的下列漏洞：netfilter: x_tables: fix percpu counter block leak on error path when creating new netns Here is the stack where we allocate percpu counter block: +-< __alloc_percpu +-< xt_percpu_counter_alloc +-< find_check_entry # {arp,ip,ip6}_tables.c +-< translate_table And it can be leaked on this code path: +-> ip6t_register_table +-> translate_table # allocates percpu counter block +-> xt_register_table # fails there is no freeing of the counter block on xt_register_table fail. Note: xt_percpu_counter_free should be called to free it like we do in do_replace through cleanup_entry helper (or in __ip6t_unregister_table). Probability of hitting this error path is low AFAICS (xt_register_table can only return ENOMEM here, as it is not replacing anything, as we are creating new netns, and it is hard to imagine that all previous allocations succeeded and after that one in xt_register_table failed). But it's worth fixing even the rare leak. (CVE-2023-53200)

  - 已修复 Linux 内核中的下列漏洞：spi: imx: Don't skip cleanup in remove's error path Returning early in a platform driver's remove callback is wrong. In this case the dma resources are not released in the error path. this is never retried later and so this is a permanent leak.
    To fix this, only skip hardware disabling if waking the device fails. (CVE-2023-53225)

AlmaLinux 9.2 主机上存在安装的程序包，该程序包受到 TuxCare ALMALINUX9.2：CLSA-2026：1782151303公告中提及的多个漏洞的影响。

  - 已修复 Linux 内核中的下列漏洞：netfilter: ebtables: fix memory leak when blob is malformed The bug fix was incomplete, it replaced crash with a memory leak. The old code had an assignment to ret embedded into the conditional, restore this. (CVE-2022-48641)

  - 已修复 Linux 内核中的下列漏洞：thermal/int340x_thermal: handle data_vault when the value is ZERO_SIZE_PTR In some case, the GDDV returns a package with a buffer which has zero length. It causes that kmemdup() returns ZERO_SIZE_PTR (0x10). Then the data_vault_read() got NULL point dereference problem when accessing the 0x10 value in data_vault. [ 71.024560] BUG: kernel NULL pointer dereference, address: 0000000000000010 This patch uses ZERO_OR_NULL_PTR() for checking ZERO_SIZE_PTR or NULL value in data_vault. (CVE-2022-48703)

  - 已修复 Linux 内核中的下列漏洞：ice: switch: fix potential memleak in ice_add_adv_recipe() When ice_add_special_words() fails, the 'rm' is not released, which will lead to a memory leak. Fix this up by going to 'err_unroll' label. Compile tested only. (CVE-2022-48709)

  - 已修复 Linux 内核中的下列漏洞：xen-netfront: Fix NULL sring after live migration A NAPI is setup for each network sring to poll data to kernel The sring with source host is destroyed before live migration and new sring with target host is setup after live migration. The NAPI for the old sring is not deleted until setup new sring with target host after migration. With busy_poll/busy_read enabled, the NAPI can be polled before got deleted when resume VM.

  - 已修复 Linux 内核中的下列漏洞：cifs: fix small mempool leak in SMB2_negotiate() In some cases of failure (dialect mismatches) in SMB2_negotiate(), after the request is sent, the checks would return -EIO when they should be rather setting rc = -EIO and jumping to neg_exit to free the response buffer from mempool.
