CVE-2026-49425
The FreeBSD kernel's compat32 subsystem contains a vulnerability in the kevent() handler. When translating a 64-bit kevent struct into a stack-declared 32-bit struct, the handler fails to zero the stack struct first. This use of an uninitialized variable allows an unprivileged user to observe a s...
CVE-2026-49424
The Linuxulator (Linux binary compatibility layer) in FreeBSD kernels contains a kernel stack disclosure vulnerability in the waitid() system call implementation. The flaw occurs because the implementation translates a FreeBSD siginfo_t struct into a stack-declared Linux siginfo_t struct without ...
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...
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...
CVE-2026-73523 COVESA Open1722 0.9.2 Stack Memory Disclosure via acf-can-listener.c Integer Truncation
COVESA Open1722 through 0.9.2 contains an integer truncation vulnerability in acf-can-listener.c that allows unauthenticated remote attackers to cause the CAN listener to transmit process stack memory onto the CAN bus by sending a rejected UDP datagram with a matching AVTP stream ID. The numcanms...
CVE-2026-12519
The WNC-M14A2A LTE-M modem driver mishandles unsolicited %NOTIFYEV: events in oncmdsocknotifyev drivers/modem/vendorstandalone/wncm14a2a.c. The response line is linearized into a fixed 40-byte stack buffer via netbuflinearize, which caps the copy at 39 bytes and returns outlen = 39. The two...

FreeBSD : FreeBSD-kernel -- Kernel stack disclosure in 32-bit compatibility support (43f9ca02-74e3-11f1-958d-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 43f9ca02-74e3-11f1-958d-bc241121aa0a advisory. The compat32 kevent handler translates a 64-bit kevent struct into a stack- declared 32-bit struct. It...
FreeBSD-kernel -- Kernel stack disclosure in 32-bit compatibility support
Problem Description: The compat32 kevent handler translates a 64-bit kevent struct into a stack- declared 32-bit struct. It did not first zero the stack struct. Impact: An unprivileged user may observe a small amount of uninitialized kernel stack data, which may contain sensitive information...
Oj: intern.c form_attr (uninitialized stack read)
Summary Oj.load in :object mode reads uninitialized stack memory and, for long keys, reads out of bounds when parsing a JSON object whose key is 254 bytes or longer. The interned bytes can surface to the caller, disclosing process stack memory. Details In ext/oj/intern.c, formattr handles the...
