CVE-2017-5123

CVE-2017-5123 PoC CVE-2017-5123 - LPE - Bypassing SMEP/SMAP. No KASLR The waitid implementation in upstream kernels did not restrict the target destination to copy information results. This can allow local users to write to otherwise protected kernel memory, which can lead to privilege escalation...

CVE-2026-49424

The Linux waitid implementation translates a FreeBSD siginfot struct into a stack-declared Linux siginfot. It did not first zero the stack struct. An unprivileged user may observe 104 bytes of uninitialized kernel stack data, which may contain sensitive information...

CVE-2026-49424

CVE-2026-49424 affects the Linux compatibility layer (Linuxulator, module linux(4)) in FreeBSD 14.3, 14.4, and 15.0 . The waitid() system call implementation translates a FreeBSD siginfo_t struct into a stack-declared Linux siginfo_t without first zeroing it, allowing an unprivileged user to obse...

CVE-2026-49424 Kernel stack disclosure in Linux compatibility layer

The Linux waitid implementation translates a FreeBSD siginfot struct into a stack-declared Linux siginfot. It did not first zero the stack struct. An unprivileged user may observe 104 bytes of uninitialized kernel stack data, which may contain sensitive information...

The vulnerability in the implementation of the waitid() system call layer of the Linuxulator kernel in FreeBSD allows a attacker to disclose protected information.

The vulnerability in the implementation of the waitid system call layer of the Linuxulator kernel in FreeBSD operating systems is related to the use of an uninitialized variable. Exploiting this vulnerability can allow an attacker to disclose sensitive information that is protected by security...

FreeBSD : FreeBSD -- Kernel stack disclosure in Linux compatibility layer (2355c475-74e3-11f1-958d-bc241121aa0a)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 2355c475-74e3-11f1-958d-bc241121aa0a advisory. The Linux waitid implementation translates a FreeBSD siginfot struct into a stack-declared Linux...
