CVSS: -EPSS: 0%CPEs: 4EXPL: 0CVE-2024-56584 – io_uring/tctx: work around xa_store() allocation error issue
https://notcve.org/view.php?id=CVE-2024-56584
In the Linux kernel, the following vulnerability has been resolved: io_uring/tctx: work around xa_store() allocation error issue syzbot triggered the following WARN_ON: WARNING: CPU: 0 PID: 16 at io_uring/tctx.c:51 __io_uring_free+0xfa/0x140 io_uring/tctx.c:51 which is the WARN_ON_ONCE(!xa_empty(&tctx->xa)); sanity check in __io_uring_free() when a io_uring_task is going through its final put. The syzbot test case includes injecting memory allocation failures, and it very much looks like xa_store() can fail one of its memory allocations and end up with ->head being non-NULL even though no entries exist in the xarray. Until this issue gets sorted out, work around it by attempting to iterate entries in our xarray, and WARN_ON_ONCE() if one is found. • https://git.kernel.org/stable/c/94ad56f61b873ffeebcc620d451eacfbdf9d40f0 https://git.kernel.org/stable/c/42882b583095dcf747da6e3af1daeff40e27033e https://git.kernel.org/stable/c/d5b2ddf1f90c7248eff9630b95895c8950f2f36d https://git.kernel.org/stable/c/7eb75ce7527129d7f1fee6951566af409a37a1c4 •

In the Linux kernel, the following vulnerability has been resolved: ovl: Filter invalid inodes with missing lookup function Add a check to the ovl_dentry_weird() function to prevent the processing of directory inodes that lack the lookup function. This is important because such inodes can cause errors in overlayfs when passed to the lowerstack. • https://git.kernel.org/stable/c/f9248e2f73fb4afe08324485e98c815ac084d166 https://git.kernel.org/stable/c/5f86e79c0b2287ffdabe6c1b305a36c4e0f40fe3 https://git.kernel.org/stable/c/749eac5a6687ec99116e0691d0d71225254654e3 https://git.kernel.org/stable/c/ff43d008bbf9b27ada434d6455f039a5ef6cee53 https://git.kernel.org/stable/c/065bf5dd21639f80e68450de16bda829784dbb8c https://git.kernel.org/stable/c/72014e7745cc8250bb8f27bd78694dfd3f1b5773 https://git.kernel.org/stable/c/c8b359dddb418c60df1a69beea01d1b3322bfe83 •
