The remote CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:7419 advisory.

  - A use-after-free vulnerability in the Linux kernel's net/sched: cls_u32 component can be exploited to     achieve local privilege escalation. When u32_change() is called on an existing filter, the whole     tcf_result struct is always copied into the new instance of the filter. This causes a problem when     updating a filter bound to a class, as tcf_unbind_filter() is always called on the old instance in the     success path, decreasing filter_cnt of the still referenced class and allowing it to be deleted, leading     to a use-after-free. We recommend upgrading past commit 3044b16e7c6fe5d24b1cdbcf1bd0a9d92d1ebd81.
    (CVE-2023-4208)

  - An out-of-bounds write vulnerability in the Linux kernel's net/sched: sch_qfq component can be exploited     to achieve local privilege escalation. The qfq_change_agg() function in net/sched/sch_qfq.c allows an out-     of-bounds write because lmax is updated according to packet sizes without bounds checks. We recommend     upgrading past commit 3e337087c3b5805fe0b8a46ba622a962880b5d64. (CVE-2023-3611)

  - A use-after-free vulnerability in the Linux kernel's net/sched: cls_fw component can be exploited to     achieve local privilege escalation. If tcf_change_indev() fails, fw_set_parms() will immediately return an     error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can     control the reference counter and set it to zero, they can cause the reference to be freed, leading to a     use-after-free vulnerability. We recommend upgrading past commit 0323bce598eea038714f941ce2b22541c46d488f.
    (CVE-2023-3776)

  - A use-after-free vulnerability in the Linux kernel's net/sched: cls_route component can be exploited to     achieve local privilege escalation. When route4_change() is called on an existing filter, the whole     tcf_result struct is always copied into the new instance of the filter. This causes a problem when     updating a filter bound to a class, as tcf_unbind_filter() is always called on the old instance in the     success path, decreasing filter_cnt of the still referenced class and allowing it to be deleted, leading     to a use-after-free. We recommend upgrading past commit b80b829e9e2c1b3f7aae34855e04d8f6ecaf13c8.

An update of the linux package has been released.

The version of kernel installed on the remote host is prior to 5.4.253-167.359. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2023-054 advisory.

    A use-after-free flaw was found in btrfs_search_slot in fs/btrfs/ctree.c in btrfs in the Linux Kernel.This     flaw allows an attacker to crash the system and possibly cause a kernel information lea (CVE-2023-1611)

    A flaw in the Linux Kernel found in the GFS2 file system. On corrupted gfs2 file systems the evict code     can try to reference the journal descriptor structure, jdesc, after it has been freed and set to NULL. It     can lead to null pointer dereference when gfs2_trans_begin being called and then fail     ingfs2_evict_inode(). (CVE-2023-3212)

    The fix for XSA-423 added logic to Linux'es netback driver to deal witha frontend splitting a packet in a     way such that not all of the headerswould come in one piece.  Unfortunately the logic introduced     theredidn't account for the extreme case of the entire packet being splitinto as many pieces as permitted     by the protocol, yet still beingsmaller than the area that's specially dealt with to keep all     (possible)headers together.  Such an unusual packet would therefore trigger abuffer overrun in the driver.
    (CVE-2023-34319)

    An out-of-bounds read vulnerability was found in Netfilter Connection Tracking (conntrack) in the Linux     kernel. This flaw allows a remote user to disclose sensitive information via the DCCP protocol.
    (CVE-2023-39197)

    A use-after-free flaw was found in net/sched/cls_fw.c in classifiers (cls_fw, cls_u32, and cls_route) in     the Linux Kernel. This flaw allows a local attacker to perform a local privilege escalation due to     incorrect handling of the existing filter, leading to a kernel information leak issue. (CVE-2023-4128)

    A flaw was found in the Linux kernel's TUN/TAP functionality. This issue could allow a local user to     bypass network filters and gain unauthorized access to some resources. The original patches fixing     CVE-2023-1076 are incorrect or incomplete. The problem is that the following upstream commits -     a096ccca6e50 (tun: tun_chr_open(): correctly initialize socket uid), - 66b2c338adce (tap: tap_open():
    correctly initialize socket uid), pass inode->i_uid to sock_init_data_uid() as the last parameter and     that turns out to not be accurate. (CVE-2023-4194)

    A use-after-free vulnerability in the Linux kernel's net/sched: cls_route component can be exploited to     achieve local privilege escalation.

    When route4_change() is called on an existing filter, the whole tcf_result struct is always copied into     the new instance of the filter. This causes a problem when updating a filter bound to a class, as     tcf_unbind_filter() is always called on the old instance in the success path, decreasing filter_cnt of the     still referenced class and allowing it to be deleted, leading to a use-after-free.

    We recommend upgrading past commit b80b829e9e2c1b3f7aae34855e04d8f6ecaf13c8. (CVE-2023-4206)
