26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: af_netlink: Fix shift out of bounds in group mask calculation When a netlink message is received, netlink_recvmsg() fills in the address of the sender. One of the fields is the 32-bit bitfield nl_groups, which carries the multicast group on which the message was received. The least significant bit corresponds to group 1, and therefore the highest group that the field can represent is 32. Above that, the UB sanitizer flags the out-of-bounds ... • https://git.kernel.org/stable/c/f7fa9b10edbb9391bdd4ec8e8b3d621d0664b198 •

CVE-2022-49196 – powerpc/pseries: Fix use after free in remove_phb_dynamic()

26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: powerpc/pseries: Fix use after free in remove_phb_dynamic() In remove_phb_dynamic() we use &phb->io_resource, after we've called device_unregister(&host_bridge->dev). But the unregister may have freed phb, because pcibios_free_controller_deferred() is the release function for the host_bridge. If there are no outstanding references when we call device_unregister() then phb will be freed out from under us. This has gone mainly unnoticed, but ... • https://git.kernel.org/stable/c/2dd9c11b9d4dfbd6c070eab7b81197f65e82f1a0 •

CVE-2022-49191 – mxser: fix xmit_buf leak in activate when LSR == 0xff

26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: mxser: fix xmit_buf leak in activate when LSR == 0xff When LSR is 0xff in ->activate() (rather unlike), we return an error. Provided ->shutdown() is not called when ->activate() fails, nothing actually frees the buffer in this case. Fix this by properly freeing the buffer in a designated label. We jump there also from the "!info->type" if now too. • https://git.kernel.org/stable/c/6769140d304731f0a3b177470a2adb4bacd9036b •

CVE-2022-49190 – kernel/resource: fix kfree() of bootmem memory again
https://notcve.org/view.php?id=CVE-2022-49190
26 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: kernel/resource: fix kfree() of bootmem memory again Since commit ebff7d8f270d ("mem hotunplug: fix kfree() of bootmem memory"), we could get a resource allocated during boot via alloc_resource(). And it's required to release the resource using free_resource(). Howerver, many people use kfree directly which will result in kernel BUG. In order to fix this without fixing every call site, just leak a couple of bytes in such corner case. • https://git.kernel.org/stable/c/ebff7d8f270d045338d9f4796014f4db429a17f9 •
