In the Linux kernel, the following vulnerability has been resolved: cgroup: Use separate src/dst nodes when preloading css_sets for migration Each cset (css_set) is pinned by its tasks. When we're moving tasks around across csets for a migration, we need to hold the source and destination csets to ensure that they don't go away while we're moving tasks about. This is done by linking cset->mg_preload_node on either the mgctx->preloaded_src_csets or mgctx->preloaded_dst_csets list. Using the same cset->mg_preload_node for both the src and dst lists was deemed okay as a cset can't be both the source and destination at the same time. Unfortunately, this overloading becomes problematic when multiple tasks are involved in a migration and some of them are identity noop migrations while others are actually moving across cgroups. For example, this can happen with the following sequence on cgroup1: #1> mkdir -p /sys/fs/cgroup/misc/a/b #2> echo $$ > /sys/fs/cgroup/misc/a/cgroup.procs #3> RUN_A_COMMAND_WHICH_CREATES_MULTIPLE_THREADS & #4> PID=$! #5> echo $PID > /sys/fs/cgroup/misc/a/b/tasks #6> echo $PID > /sys/fs/cgroup/misc/a/cgroup.procs the process including the group leader back into a. In this final migration, non-leader threads would be doing identity migration while the group leader is doing an actual one. After #3, let's say the whole process was in cset A, and that after #4, the leader moves to cset B. Then, during #6, the following happens: 1. cgroup_migrate_add_src() is called on B for the leader. 2. cgroup_migrate_add_src() is called on A for the other threads. 3. cgroup_migrate_prepare_dst() is called. It scans the src list. 4. It notices that B wants to migrate to A, so it tries to A to the dst list but realizes that its ->mg_preload_node is already busy. 5. and then it notices A wants to migrate to A as it's an identity migration, it culls it by list_del_init()'ing its ->mg_preload_node and putting references accordingly. 6. The rest of migration takes place with B on the src list but nothing on the dst list. This means that A isn't held while migration is in progress. If all tasks leave A before the migration finishes and the incoming task pins it, the cset will be destroyed leading to use-after-free. This is caused by overloading cset->mg_preload_node for both src and dst preload lists. We wanted to exclude the cset from the src list but ended up inadvertently excluding it from the dst list too. This patch fixes the issue by separating out cset->mg_preload_node into ->mg_src_preload_node and ->mg_dst_preload_node, so that the src and dst preloadings don't interfere with each other.

    cgroup: Use separate src/dst nodes when preloading css_sets for migration (CVE-2022-49647)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In the Linux kernel, the following vulnerability has been resolved: cgroup: Use separate src/dst nodes     when preloading css_sets for migration Each cset (css_set) is pinned by its tasks. When we're moving tasks     around across csets for a migration, we need to hold the source and destination csets to ensure that they     don't go away while we're moving tasks about. This is done by linking cset->mg_preload_node on either the     mgctx->preloaded_src_csets or mgctx->preloaded_dst_csets list. Using the same cset->mg_preload_node for     both the src and dst lists was deemed okay as a cset can't be both the source and destination at the same     time. Unfortunately, this overloading becomes problematic when multiple tasks are involved in a migration     and some of them are identity noop migrations while others are actually moving across cgroups. For     example, this can happen with the following sequence on cgroup1: #1> mkdir -p /sys/fs/cgroup/misc/a/b #2>     echo $$ > /sys/fs/cgroup/misc/a/cgroup.procs #3> RUN_A_COMMAND_WHICH_CREATES_MULTIPLE_THREADS & #4> PID=$!     #5> echo $PID > /sys/fs/cgroup/misc/a/b/tasks #6> echo $PID > /sys/fs/cgroup/misc/a/cgroup.procs the     process including the group leader back into a. In this final migration, non-leader threads would be doing     identity migration while the group leader is doing an actual one. After #3, let's say the whole process     was in cset A, and that after #4, the leader moves to cset B. Then, during #6, the following happens: 1.
    cgroup_migrate_add_src() is called on B for the leader. 2. cgroup_migrate_add_src() is called on A for the     other threads. 3. cgroup_migrate_prepare_dst() is called. It scans the src list. 4. It notices that B     wants to migrate to A, so it tries to A to the dst list but realizes that its ->mg_preload_node is already     busy. 5. and then it notices A wants to migrate to A as it's an identity migration, it culls it by     list_del_init()'ing its ->mg_preload_node and putting references accordingly. 6. The rest of migration     takes place with B on the src list but nothing on the dst list. This means that A isn't held while     migration is in progress. If all tasks leave A before the migration finishes and the incoming task pins     it, the cset will be destroyed leading to use-after-free. This is caused by overloading     cset->mg_preload_node for both src and dst preload lists. We wanted to exclude the cset from the src list     but ended up inadvertently excluding it from the dst list too. This patch fixes the issue by separating     out cset->mg_preload_node into ->mg_src_preload_node and ->mg_dst_preload_node, so that the src and dst     preloadings don't interfere with each other. (CVE-2022-49647)

Note that Nessus relies on the presence of the package as reported by the vendor.

    A flaw was found in the Linux kernel's KVM when attempting to set a SynIC IRQ. This issue makes it     possible for a misbehaving VMM to write to SYNIC/STIMER MSRs, causing a NULL pointer dereference.

    An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race     condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale     TLB entries. This only occurs in situations with VM_PFNMAP VMAs. (CVE-2022-39188)

    A race condition in the Linux kernel's EFI capsule loader driver was found in the way it handled write and     flush operations on the device node of the EFI capsule. A local user could potentially use this flaw to     crash the system. (CVE-2022-40307)

    In the Linux kernel, the following vulnerability has been resolved: ipv6: sr: fix out-of-bounds read when     setting HMAC data.

    In the Linux kernel, the following vulnerability has been resolved:

    mm/slub: add missing TID updates on slab deactivation (CVE-2022-49700)

    The upstream advisory describes this issue as follows:

    This vulnerability allows local attackers to disclose sensitive information on affected installations of     the Linux Kernel. An attacker must first obtain the ability to execute high-privileged code on the target     system in order to exploit this vulnerability.

    The specific flaw exists within the processing of seg6 attributes. The issue results from the lack of     proper validation of user-supplied data, which can result in a read past the end of an allocated buffer.
    An attacker can leverage this in conjunction with other vulnerabilties to escalate privileges and execute     arbitrary code in the context of the kernel. (CVE-2023-2860)
