The CentOS Linux 8.5 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS8.5:CLSA-2026:1792979985 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: net: bridge: fix vlan tunnel dst     refcnt when egressing The egress tunnel code uses dst_clone() and directly sets the result which is wrong     because the entry might have 0 refcnt or be already deleted, causing number of problems. It also triggers     the WARN_ON() in dst_hold()[1] when a refcnt couldn't be taken. Fix it by using dst_hold_safe() and     checking if a reference was actually taken before setting the dst.

  - In the Linux kernel, the following vulnerability has been resolved: net: bridge: fix vlan tunnel dst null     pointer dereference This patch fixes a tunnel_dst null pointer dereference due to lockless access in the     tunnel egress path. When deleting a vlan tunnel the tunnel_dst pointer is set to NULL without waiting a     grace period (i.e. while it's still usable) and packets egressing are dereferencing it without checking.
    Use READ/WRITE_ONCE to annotate the lockless use of tunnel_id, use RCU for accessing tunnel_dst and make     sure it is read only once and checked in the egress path. The dst is already properly RCU protected so we     don't need to do anything fancy than to make sure tunnel_id and tunnel_dst are read only once and checked     in the egress path. (CVE-2021-47223)

  - In the Linux kernel, the following vulnerability has been resolved: bpf: Guard stack limits against 32bit     overflow This patch promotes the arithmetic around checking stack bounds to be done in the 64-bit domain,     instead of the current 32bit. The arithmetic implies adding together a 64-bit register with a int offset.
    The register was checked to be below 1<<29 when it was variable, but not when it was fixed. The offset     either comes from an instruction (in which case it is 16 bit), from another register (in which case the     caller checked it to be below 1<<29 [1]), or from the size of an argument to a kfunc (in which case it can     be a u32 [2]). Between the register being inconsistently checked to be below 1<<29, and the offset being     up to an u32, it appears that we were open to overflowing the `int`s which were currently used for     arithmetic.

  - In the Linux kernel, the following vulnerability has been resolved: cifs: fix session state check in     reconnect to avoid use-after-free issue Don't collect exiting session in smb2_reconnect_server(), because     it will be released soon. Note that the exiting session will stay in server->smb_ses_list until it     complete the cifs_free_ipc() and logoff() and then delete itself from the list. (CVE-2023-53794)

  - In the Linux kernel, the following vulnerability has been resolved: ubi: Fix use-after-free when volume     resizing failed There is an use-after-free problem reported by KASAN:

    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For Debian 11 bullseye, these problems have been fixed in version     5.10.262-1. This version additionally includes many more bug fixes     from stable updates 5.10.260-5.10.262.

    We recommend that you upgrade your linux packages.
