https://notcve.org/view.php?id=CVE-2024-53173
In the Linux kernel, the following vulnerability has been resolved: NFSv4.0: Fix a use-after-free problem in the asynchronous open() Yang Erkun reports that when two threads are opening files at the same time, and are forced to abort before a reply is seen, then the call to nfs_release_seqid() in nfs4_opendata_free() can result in a use-after-free of the pointer to the defunct rpc task of the other thread. The fix is to ensure that if the RPC call is aborted before the call to nfs_wait_on_sequence() is complete, then we must call nfs_release_seqid() in nfs4_open_release() before the rpc_task is freed. • https://git.kernel.org/stable/c/24ac23ab88df5b21b5b2df8cde748bf99b289099 https://git.kernel.org/stable/c/1cfae9575296f5040cdc84b0730e79078c081d2d https://git.kernel.org/stable/c/7bf6bf130af8ee7d93a99c28a7512df3017ec759 https://git.kernel.org/stable/c/5237a297ffd374a1c4157a53543b7a69d7bbbc03 https://git.kernel.org/stable/c/2ab9639f16b05d948066a6c4cf19a0fdc61046ff https://git.kernel.org/stable/c/ba6e6c04f60fe52d91520ac4d749d372d4c74521 https://git.kernel.org/stable/c/229a30ed42bb87bcb044c5523fabd9e4f0e75648 https://git.kernel.org/stable/c/e2277a1d9d5cd0d625a4fd7c04fce2b53 •

In the Linux kernel, the following vulnerability has been resolved: sh: cpuinfo: Fix a warning for CONFIG_CPUMASK_OFFSTACK When CONFIG_CPUMASK_OFFSTACK and CONFIG_DEBUG_PER_CPU_MAPS are selected, cpu_max_bits_warn() generates a runtime warning similar as below when showing /proc/cpuinfo. Fix this by using nr_cpu_ids (the runtime limit) instead of NR_CPUS to iterate CPUs.

CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-53150 – ALSA: usb-audio: Fix out of bounds reads when finding clock sources
https://notcve.org/view.php?id=CVE-2024-53150
In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Fix out of bounds reads when finding clock sources The current USB-audio driver code doesn't check bLength of each descriptor at traversing for clock descriptors. That is, when a device provides a bogus descriptor with a shorter bLength, the driver might hit out-of-bounds reads. For addressing it, this patch adds sanity checks to the validator functions for the clock descriptor traversal. When the descriptor length is shorter than expected, it's skipped in the loop. For the clock source and clock multiplier descriptors, we can just check bLength against the sizeof() of each descriptor type. OTOH, the clock selector descriptor of UAC2 and UAC3 has an array of bNrInPins elements and two more fields at its tail, hence those have to be checked in addition to the sizeof() check. • https://git.kernel.org/stable/c/a632bdcb359fd8145e86486ff8612da98e239acd https://git.kernel.org/stable/c/45a92cbc88e4013bfed7fd2ccab3ade45f8e896b https://git.kernel.org/stable/c/ab011f7439d9bbfd34fd3b9cef4b2d6d952c9bb9 https://git.kernel.org/stable/c/da13ade87a12dd58829278bc816a61bea06a56a9 https://git.kernel.org/stable/c/74cb86e1006c5437b1d90084d22018da30fddc77 https://git.kernel.org/stable/c/ea0fa76f61cf8e932d1d26e6193513230816e11d https://git.kernel.org/stable/c/096bb5b43edf755bc4477e64004fa3a20539ec2f https://git.kernel.org/stable/c/a3dd4d63eeb452cfb064a13862fb376ab •
