CVE-2023-53999 net/mlx5e: TC, Fix internal port memory leak

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: TC, Fix internal port memory leak The flow rule can be splited, and the extra postact rules are added to postact table. It's possible to trigger memleak when the rule forwards packets from internal port and over tunnel...

CVE-2025-38349

In the Linux kernel, the following vulnerability has been resolved: eventpoll: don't decrement ep refcount while still holding the ep mutex Jann Horn points out that epoll is decrementing the ep refcount and then doing a mutexunlock&ep-mtx; afterwards. That's very wrong, because it can lead to a...

grub2: fs/hfs+: refcount can be decremented twice

A flaw was found in grub2. When failing to mount an HFS+ grub, the hfsplus filesystem driver doesn't properly set an ERRNO value. This issue may lead to a NULL pointer access...

CVE-2024-44991

CVE-2024-44991 affects the Linux kernel TCP stack: concurrent calls to tcp_sk_exit_batch() can race with inet_twsk_purge() across dying netns, risking timewait sockets of the exiting netns. The root cause: after the net/core/net_namespace change (commit that batches inet_twsk_purge), tcp_twsk_pur...

CVE-2024-27054

The CVE-2024-27054 issue resides in the Linux kernel s390/dasd path where the module refcount could be decremented twice due to manual handling of refcounts after device association. The vulnerability results in an artificial decrease of the module’s refcount on each error path, rather than keepi...

CVE-2019-19530

A use-after-free flaw was found in the acmprobe USB subsystem in the Linux kernel. A race condition occurs when a destroy procedure is initiated allowing the refcount to decrement on the interface so early that it is never under counted. A malicious USB device is required for exploit. System...
