  - 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)

    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     6.1.129-1~deb11u1.  This additionally includes many more bug fixes     from stable update 6.1.129, and a fix for a regression affecting some     Rockchip SoCs.

    We recommend that you upgrade your linux-6.1 packages.

    For the detailed security status of linux-6.1 please refer to     its security tracker page at:
    https://security-tracker.debian.org/tracker/linux-6.1
