CVE-2026-80565

This Linux kernel vulnerability affects the crypto qce (Qualcomm Crypto Engine) driver, specifically the devm_qce_register_algs function. The root cause is an error-path bug : when ops->register_algs() fails during algorithm registration, the error handler repeatedly invokes the same ops->u...

CVE-2026-80522 crypto: tegra - fix rctx->cryptlen calculation in tegra_gcm_do_one_req()

In the Linux kernel, the following vulnerability has been resolved: crypto: tegra - fix rctx-cryptlen calculation in tegragcmdoonereq Perform rctx-cryptlen calculation in tegragcmdoonereq the same way it is done in tegraccmcryptinit. The current formulae may lead to a crash if a caller does not...

CVE-2026-80522

CVE-2026-80522 affects the Linux kernel Tegra crypto driver . The root cause is an incorrect rctx->cryptlen calculation in tegra_gcm_do_one_req() when the caller has not invoked tegra_gcm_setauthsize(), leaving ctx->authsize at zero. This results in a write beyond the rctx->dst_sg buffer...

CVE-2026-80520 ovpn: fix NULL dereference when killing missing key

In the Linux kernel, the following vulnerability has been resolved: ovpn: fix NULL dereference when killing missing key ovpncryptokillkey assumes both crypto slots are populated and dereferences each slot before checking it. That is not guaranteed: a peer can have only one installed key, and the...

CVE-2026-80520

A NULL pointer dereference in the Linux kernel's ovpn (OpenVPN) module can lead to a denial of service (CVSS 3.1: 7.5, HIGH). The function ovpn_crypto_kill_key assumes both crypto slots are populated and dereferences each before checking for NULL. Since a peer can have only one installed key, the...

CVE-2026-80519 ovpn: finish crypto callback cleanup before peer release

In the Linux kernel, the following vulnerability has been resolved: ovpn: finish crypto callback cleanup before peer release Crypto completion callbacks hold both key-slot and peer references. The peer reference pins the netdev, and dropping the last peer reference can let netdev unregistration a...

CVE-2026-80519 ovpn: finish crypto callback cleanup before peer release

The peer reference pins the netdev, and dropping the last peer reference can let netdev unregistration a...

CVE-2026-80519

CVE-2026-80519 affects the Linux kernel OpenVPN module (ovpn) due to an incorrect ordering of reference cleanup in crypto completion callbacks. Specifically, the peer reference (which pins the netdev) is dropped before the callback finishes its own cleanup, allowing ovpn_crypto_key_slot_put to sc...

CVE-2026-74750

CVE-2026-74750 affects the Linux kernel's ovpn (OpenVPN) module . The root cause is that key slots are released via an RCU callback, which calls crypto_free_aead —a function that may sleep when an asynchronous or hardware crypto implementation has pending teardown work. Calling a sleeping functio...
