The remote CentOS Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the kernel-5.14.0-580.el9 build changelog.

  - In the Linux kernel, the following vulnerability has been resolved: ima: Fix potential memory leak in     ima_init_crypto() On failure to allocate the SHA1 tfm, IMA fails to initialize and exits without freeing     the ima_algo_array. Add the missing kfree() for ima_algo_array to avoid the potential memory leak.
    (CVE-2022-49627)

  - In the Linux kernel, the following vulnerability has been resolved: pfifo_tail_enqueue: Drop new packet     when sch->limit == 0 Expected behaviour: In case we reach scheduler's limit, pfifo_tail_enqueue() will     drop a packet in scheduler's queue and decrease scheduler's qlen by one. Then, pfifo_tail_enqueue()     enqueue new packet and increase scheduler's qlen by one. Finally, pfifo_tail_enqueue() return     `NET_XMIT_CN` status code. Weird behaviour: In case we set `sch->limit == 0` and trigger     pfifo_tail_enqueue() on a scheduler that has no packet, the 'drop a packet' step will do nothing. This     means the scheduler's qlen still has value equal 0. Then, we continue to enqueue new packet and increase     scheduler's qlen by one. In summary, we can leverage pfifo_tail_enqueue() to increase qlen by one and     return `NET_XMIT_CN` status code. The problem is: Let's say we have two qdiscs: Qdisc_A and Qdisc_B. -     Qdisc_A's type must have '->graft()' function to create parent/child relationship. Let's say Qdisc_A's     type is `hfsc`. Enqueue packet to this qdisc will trigger `hfsc_enqueue`. - Qdisc_B's type is     pfifo_head_drop. Enqueue packet to this qdisc will trigger `pfifo_tail_enqueue`. - Qdisc_B is configured     to have `sch->limit == 0`. - Qdisc_A is configured to route the enqueued's packet to Qdisc_B. Enqueue     packet through Qdisc_A will lead to: - hfsc_enqueue(Qdisc_A) -> pfifo_tail_enqueue(Qdisc_B) -     Qdisc_B->q.qlen += 1 - pfifo_tail_enqueue() return `NET_XMIT_CN` - hfsc_enqueue() check for     `NET_XMIT_SUCCESS` and see `NET_XMIT_CN` => hfsc_enqueue() don't increase qlen of Qdisc_A. The whole     process lead to a situation where Qdisc_A->q.qlen == 0 and Qdisc_B->q.qlen == 1. Replace 'hfsc' with other     type (for example: 'drr') still lead to the same problem. This violate the design where parent's qlen     should equal to the sum of its childrens'qlen. Bug impact: This issue can be used for user->kernel     privilege escalation when it is reachable. (CVE-2025-21702)

  - In the Linux kernel, the following vulnerability has been resolved: ipv6: use RCU protection in     ip6_default_advmss() ip6_default_advmss() needs rcu protection to make sure the net structure it reads     does not disappear. (CVE-2025-21765)

  - In the Linux kernel, the following vulnerability has been resolved: vxlan: check vxlan_vnigroup_init()     return value vxlan_init() must check vxlan_vnigroup_init() success otherwise a crash happens later,     spotted by syzbot.
