kernel: net/sched: cls_route: fix fastmap use-after-free on filter

A flaw was found in the Linux kernel's net/sched: clsroute component. A race condition exists in the route4 classifier's fastmap cache, where a reader can re-cache a pointer to a filter that has already been freed by a writer. This can lead to a use-after-free condition, allowing subsequent packe...

kernel: svcrdma: Validate Read chunk positions before reconstruction

A flaw was found in the svcrdma component of the Linux kernel. A remote attacker can exploit this vulnerability by supplying a crafted RPC/RDMA Read chunk position field that is not properly validated against the received inline body length. This can lead to an underflow, exposing adjacent slab...

kernel: Linux kernel: Denial of Service due to use-after-free in act_tunnel_key

A flaw was found in the Linux kernel's acttunnelkey module, which manages network traffic tunneling. A race condition, where multiple operations occur in an unpredictable order, can lead to a use-after-free vulnerability. This allows a local attacker to corrupt memory, potentially causing the...

kernel: md/raid5-ppl: fix use-after-free in ppl_do_flush()

A flaw was found in the Linux kernel. A local attacker can cause a Denial of Service DoS or potentially escalate privileges through a use-after-free vulnerability in the RAID-5 Partial Parity Log PPL component. During flush operations, the system improperly continues to access an input/output I/O...

kernel: ASoC: SOF: ipc3-control: Fix heap overflow in bytes_ext put/get

A flaw was found in the Advanced Linux Sound Architecture ALSA Sound Open Firmware SOF ipc3-control component of the Linux kernel. This vulnerability, a heap overflow, occurs due to incorrect bounds checks when handling user data lengths. An unprivileged local user can exploit this to write past...

kernel: ALSA: usx2y: bound the hwdep mmap fault offset

A flaw was found in the Advanced Linux Sound Architecture ALSA usx2y driver in the Linux kernel. A local attacker, by opening the hwdep node of an attached US-X2Y device, could exploit an unbounded memory mapping mmap fault offset. This allows read-write access to arbitrary kernel memory,...

kernel: udp: fix potential use-after-free in tunnel segmentation

A flaw was found in the Linux kernel's UDP User Datagram Protocol tunnel segmentation. This vulnerability arises when the system attempts to process network packets, specifically in the skbudptunnelsegment function. An attacker could potentially exploit a use-after-free condition, where the syste...
