Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
In the Linux kernel, the following vulnerability has been resolved: btrfs: fix uninitialized pointer free on read_alloc_one_name() error The function read_alloc_one_name() does not initialize the name field of the passed fscrypt_str struct if kmalloc fails to allocate the corresponding buffer. Thus, it is not guaranteed that fscrypt_str.name is initialized when freeing it. This is a follow-up to the linked patch that fixes the remaining instances of the bug introduced by commit e43eec81c516 ("btrfs: use struct qstr instead of name and namelen pairs").

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Recommended fix High confidence

Linux kernel 6.1.114 / 6.6.58 / 6.11.5 / 6.12.1 (depending on your branch)

  1. Identify the currently running kernel version using `uname -r`
  2. Determine which version range your current kernel falls into based on the affected versions list
  3. For kernels in the 6.1.x branch (>=6.1.57, <6.1.114): upgrade to kernel version 6.1.114 or later
  4. For kernels in the 6.2-6.5.x branch: upgrade to kernel version 6.6.58 or later
  5. For kernels in the 6.7-6.11.x branch: upgrade to kernel version 6.11.5 or later
  6. For kernel version 6.12.x: upgrade to kernel version 6.12.1 or later
  7. Reboot the system to apply the new kernel
  8. Verify the fix is applied by checking the kernel version after reboot
Caveat Kernel upgrades may require rebuilding out-of-tree kernel modules; ensure compatibility with your distribution's kernel package before upgrading
