kernel: net/ipv6: ioam6: prevent schema length wraparound in trace fill

A flaw was found in the Linux kernel's IPv6 In-situ Operations, Administration, and Maintenance IOAM6 trace fill functionality. An integer overflow vulnerability exists in the ioam6filltracedata function, where the schema length calculation can wrap around due to being stored in an 8-bit unsigned...

kernel: procfs: fix missing RCU protection when reading real_parent in do_task_stat()

A flaw was found in the Linux kernel's procfs component. When reading /proc/pid/stat, the dotaskstat function accesses task-realparent without proper Read-Copy-Update RCU protection. This missing protection creates a race condition, which can lead to a Use-After-Free UAF vulnerability. A local...

kernel: Arm Processors: Privilege escalation or information disclosure via writes to higher exception level resources

A flaw was found in the Linux kernel on ARM processors. A race condition in Translation Lookaside Buffer Invalidation TLBI operations during memory permission changes allows a local attacker to write to memory resources owned by higher privilege levels. This could allow an unprivileged local...

kernel: netfilter: nfnetlink_cthelper: fix OOB read in nfnl_cthelper_dump_table()

A flaw was found in the Linux kernel's nfnetlinkcthelper component. This vulnerability, an out-of-bounds read, occurs in the nfnlcthelperdumptable function when a network connection tracking helper is removed during a dump operation, leading to a bypassed bounds check. A local attacker could...
