CVE-2026-64375

A flaw was found in the Linux kernel's proc filesystem. A local attacker with low privileges could exploit a race condition within the ptracemayaccess function when handling file descriptor links. This vulnerability arises because the system performs multiple task lookups without proper...

UBUNTU-CVE-2026-64422

In the Linux kernel, the following vulnerability has been resolved: net: ipv4: bound TCP reordering sysctl writes and MTU probe sizes Reject invalid net.ipv4.tcpreordering values before they reach TCP socket state. The sysctl is stored as an int but copied into the u32 tp-reordering field for new...

CVE-2026-64469

CVE-2026-64469 is about a use-after-free in the Linux kernel Binder subsystem (binder_thread_release). The issue occurs when a thread exits and the code walks the transaction stack to clear t->from and t->to_proc; if a process dies in parallel, some transactions may be freed without holding...

In the Linux kernel, the following vulnerability has been resolved: proc: protect ptracemayaccess with execupdatelock FD links procpidgetlink and procpidreadlink currently look up the task from the pid once, then do the ptrace access check on that task, then look up the task from the pid a second...

CVE-2026-64375

In CVE-2026-64375, the Linux kernel fix addresses a race in ptrace access checks. Previously proc_pid_get_link() and proc_pid_readlink() looked up the task from the pid twice (before and after the check). The patch passes the task to the ->proc_get_link() handler and adds call_proc_get_link() ...

CVE-2026-64371

The CVE-2026-64371 entry concerns a Linux kernel procfs issue where ptrace_may_access() was called without exec_update_lock. The vulnerability has been resolved by ensuring proper locking or using mm_access(): affected paths include do_task_stat(), proc_pid_wchan(), proc_map_files_lookup(), proc_...
