CVE-2026-74735

In the Linux kernel, the following vulnerability has been resolved: l2tp: fix tunnel and session refcount leak on seqfile release In pppol2tpprocopen and l2tpdfsseqopen, iteration state pd-tunnel and pd-session is kept in seqfile private data to allow iteration across multiple read system calls...

CVE-2026-74735

CVE-2026-74735 affects the Linux kernel's L2TP (Layer 2 Tunneling Protocol) implementation. In pppol2tp_proc_open() and l2tp_dfs_seq_open(), iteration state (pd->tunnel and pd->session) is stored in seq_file private data to support multi-read() iteration. If a local user closes /proc/net/pp...

CVE-2026-49415

A TOCTOU race condition exists in the FreeBSD kernel during the execve(2) system call when executing a SUID binary . The kernel installs the new virtual address space before updating process credentials, creating a window where a local unprivileged user (running as the same user) can access and m...

EUVD-2026-62236

During execve2 of a SUID binary, the new virtual address space is installed before the process credentials are updated. During this window, a process running as the same user can access the target process's memory via procfs or linprocfs, because the kernel's debugging permission check still saw...

CVE-2026-49415 Local privilege escalation via execve(2) TOCTOU race

During execve2 of a SUID binary, the new virtual address space is installed before the process credentials are updated. During this window, a process running as the same user can access the target process's memory via procfs or linprocfs, because the kernel's debugging permission check still saw...

CVE-2026-72118

A flaw was found in the Linux kernel's Controller Area Network CAN Broadcast Manager BCM module. A data race condition, occurring when multiple central processing units CPUs simultaneously process CAN frames, can lead to incorrect statistics being reported. This could result in a bogus or negativ...

UBUNTU-CVE-2026-74479

In the Linux kernel, the following vulnerability has been resolved: net: pktgen: fix proc entry use-after-free pktgenchangename replaces pktdev-entry while holding t-iflock. pktgenremovedevice removes the same entry before remdevfromiflist takes that lock. This allows the following interleaving:...

CVE-2026-72297 net: atm: reject out-of-range traffic classes in QoS validation

In the Linux kernel, the following vulnerability has been resolved: net: atm: reject out-of-range traffic classes in QoS validation Reject ATM traffic classes above ATMANYCLASS in checktp. SOATMQOS stores the supplied QoS after checkqos succeeds, so accepting larger values leaves invalid...
