Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Linux kernel versions with the UFS core driver are affected by a flaw in how UFS string descriptors are validated. A UFS device could return a malformed string descriptor, causing the kernel to read beyond the descriptor buffer. The source gives few details on the exact impact or required access. The fix is in the upstream kernel stable releases; upgrade to a kernel version that includes these changes, such as 6.1.191, 6.6.160, 6.12.114, or 6.18.57 or later in their series. No workaround is listed.
