CVE-2026-31431-CopyFail-static-ELF--POC

CVE-2026-31431: Copy Fail - ELF statico da 587 byte Non ho trovato io questo bug. Il merito va a Xint Code / Theori. Questo repo è la mia interpretazione su come rendere l'exploit il più piccolo possibile - un ELF x8664 scritto a mano che esegue l'intero LPE in 587 byte. Niente libc, niente linke...

CVE-2026-80543

A flaw was found in the Linux kernel's s390/zcrypt component. When copying user-space messages into a kernel buffer, the system fails to properly pad the message to a 4-byte length. This oversight can lead to up to three bytes of uninitialized kernel memory being exposed to the crypto card...

CVE-2026-74750

A flaw was found in the Linux kernel's ovpn module. This vulnerability arises from an incorrect handling of cryptographic resource freeing, where a function that requires the ability to pause sleep is executed in a context that does not allow it. This improper resource management could lead to...

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...

EUVD-2026-66580

In the Linux kernel, the following vulnerability has been resolved: ovpn: defer key slot crypto freeing to workqueue Key slots are released through a kref and the existing release path frees the AEAD transforms from an RCU callback. That is not safe for all crypto implementations: cryptofreeaead...

EUVD-2026-66586

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...

EUVD-2026-66585

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...
