https://notcve.org/view.php?id=CVE-2022-49812
01 May 2025 — In the Linux kernel, the following vulnerability has been resolved: bridge: switchdev: Fix memory leaks when changing VLAN protocol The bridge driver can offload VLANs to the underlying hardware either via switchdev or the 8021q driver. When the former is used, the VLAN is marked in the bridge driver with the 'BR_VLFLAG_ADDED_BY_SWITCHDEV' private flag. To avoid the memory leaks mentioned in the cited commit, the bridge driver will try to delete a VLAN via the 8021q driver if the VLAN is not marked with the... • https://git.kernel.org/stable/c/279737939a8194f02fa352ab4476a1b241f44ef4 •

01 May 2025 — In the Linux kernel, the following vulnerability has been resolved: netfs: Fix missing xas_retry() calls in xarray iteration netfslib has a number of places in which it performs iteration of an xarray whilst being under the RCU read lock. It *should* call xas_retry() as the first thing inside of the loop and do "continue" if it returns true in case the xarray walker passed out a special value indicating that the walk needs to be redone from the root[*]. Fix this by adding the missing retry checks. [*] I won... • https://git.kernel.org/stable/c/3d3c95046742e4eebaa4b891b0b01cbbed94ebbd •
