05 Nov 2024 — In the Linux kernel, the following vulnerability has been resolved: nfsd: fix race between laundromat and free_stateid There is a race between laundromat handling of revoked delegations and a client sending free_stateid operation. Laundromat thread finds that delegation has expired and needs to be revoked so it marks the delegation stid revoked and it puts it on a reaper list but then it unlock the state lock and the actual delegation revocation happens without the lock. Once the stid is marked revoked a ... • https://git.kernel.org/stable/c/2d4a532d385f635ab8243b88db3136bb52a0bc29 • CWE-416: Use After Free •

Both functions were originally written for use with kprobes, and access memory with plain C accesses. When uprobes was added, these were reused unmodified even though they cannot safely access user memory. There are three key problems: 1) The plain C accesses do not have corresponding... • https://git.kernel.org/stable/c/9842ceae9fa8deae141533d52a6ead7666962c09 •
