In the Linux kernel, the following vulnerability has been resolved: mm: swap: check for stable address space before operating on the VMA It is possible to hit a zero entry while traversing the vmas in unuse_mm() called from swapoff path and accessing it causes the OOPS: Unable to handle kernel NULL pointer dereference at virtual address 0000000000000446--> Loading the memory from offset 0x40 on the XA_ZERO_ENTRY as address. Mem abort info: ESR = 0x0000000096000005 EC = 0x25: DABT (current EL), IL = 32 bits SET = 0, FnV = 0 EA = 0, S1PTW = 0 FSC = 0x05: level 1 translation fault The issue is manifested from the below race between the fork() on a process and swapoff: fork(dup_mmap()) swapoff(unuse_mm) --------------- ----------------- 1) Identical mtree is built using __mt_dup(). 2) copy_pte_range()--> copy_nonpresent_pte(): The dst mm is added into the mmlist to be visible to the swapoff operation. 3) Fatal signal is sent to the parent process(which is the current during the fork) thus skip the duplication of the vmas and mark the vma range with XA_ZERO_ENTRY as a marker for this process that helps during exit_mmap(). 4) swapoff is tried on the 'mm' added to the 'mmlist' as part of the 2. 5) unuse_mm(), that iterates through the vma's of this 'mm' will hit the non-NULL zero entry and operating on this zero entry as a vma is resulting into the oops. The proper fix would be around not exposing this partially-valid tree to others when droping the mmap lock, which is being solved with [1]. A simpler solution would be checking for MMF_UNSTABLE, as it is set if mm_struct is not fully initialized in dup_mmap(). Thanks to Liam/Lorenzo/David for all the suggestions in fixing this issue.

ubuntu_linux USN-8126-1: Ubuntu 22.04 LTS : Linux kernel (Azure) vulnerabilities (USN-8126-1)

The remote Ubuntu 22.04 LTS / 24.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8095-1 advisory.

    Qualys discovered that several vulnerabilities existed in the AppArmor Linux kernel Security Module (LSM).
    An unprivileged local attacker could use these issues to load, replace, and remove arbitrary AppArmor     profiles causing denial of service, exposure of sensitive information (kernel memory), local privilege     escalation, or possibly escape a container. (LP: #2143853)

Tenable has extracted the preceding description block directly from the Ubuntu 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 remote Ubuntu 22.04 LTS / 24.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8100-1 advisory.

    Qualys discovered that several vulnerabilities existed in the AppArmor Linux kernel Security Module (LSM).
    An unprivileged local attacker could use these issues to load, replace, and remove arbitrary AppArmor     profiles causing denial of service, exposure of sensitive information (kernel memory), local privilege     escalation, or possibly escape a container. (LP: #2143853)

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.

  - mm: swap: check for stable address space before operating on the VMA It is possible to hit a zero entry     while traversing the vmas in unuse_mm() called from swapoff path and accessing it causes the OOPS: Unable     to handle kernel NULL pointer dereference at virtual address 0000000000000446--> Loading the memory from     offset 0x40 on the XA_ZERO_ENTRY as address. Mem abort info: ESR = 0x0000000096000005 EC = 0x25: DABT     (current EL), IL = 32 bits SET = 0, FnV = 0 EA = 0, S1PTW = 0 FSC = 0x05: level 1 translation fault The     issue is manifested from the below race between the fork() on a process and swapoff: fork(dup_mmap())     swapoff(unuse_mm) --------------- ----------------- 1) Identical mtree is built using __mt_dup(). 2)     copy_pte_range()--> copy_nonpresent_pte(): The dst mm is added into the mmlist to be visible to the     swapoff operation. 3) Fatal signal is sent to the parent process(which is the current during the fork)     thus skip the duplication of the vmas and mark the vma range with XA_ZERO_ENTRY as a marker for this     process that helps during exit_mmap(). 4) swapoff is tried on the 'mm' added to the 'mmlist' as part of     the 2. 5) unuse_mm(), that iterates through the vma's of this 'mm' will hit the non-NULL zero entry and     operating on this zero entry as a vma is resulting into the oops. The proper fix would be around not     exposing this partially-valid tree to others when droping the mmap lock, which is being solved with [1]. A     simpler solution would be checking for MMF_UNSTABLE, as it is set if mm_struct is not fully initialized in     dup_mmap(). Thanks to Liam/Lorenzo/David for all the suggestions in fixing this issue. (CVE-2025-39992)

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