High 7.1CVE-2026-49413 Public exploit
Flaw in Linuxulator execution of setugid binaries
The Linuxulator determined whether a binary was set-user-ID or set-group-ID by checking the P_SUGID process flag. During execve(2), this flag is not yet set at the point where the auxiliary vector is constructed, so AT_SECURE was incorrectly set to zero for s…

High 7.8CVE-2026-45258 Public exploit
Multiple vulnerabilities in the sound(4) mmap path
dsp_mmap_single() validated the requested mapping by checking the sum of the user-supplied offset and length against the buffer size. This addition could overflow, so that a large offset and length wrapped around and passed the check. The offset was then narr…

High 7.0CVE-2026-49417 Public exploit
Multiple vulnerabilities in the sound(4) mmap path
Second, the audio buffer backing a mapping could be freed when the device was closed even though the mapping remained valid. The freed memory could then be reused elsewhere while still accessible through the stale mapping. The /dev/dsp device nodes are world-…

High 7.8CVE-2026-45250 Public exploit
Stack buffer overflow via setcred(2)
The setcred(2) system call is only available to privileged users. However, before the privilege level of the caller is checked, the user-supplied list of supplementary groups is copied into a fixed-size kernel stack buffer without first validating its length.…

High 7.8CVE-2026-7270 Public exploit
Local privilege escalation via execve()
An operator precedence bug in the kernel results in a scenario where a buffer overflow causes attacker-controlled data to overwrite adjacent execve(2) argument buffers. The bug may be exploitable by an unprivileged user to obtain superuser privileges.

High 8.8CVE-2026-4747 Public exploit
Remote code execution via RPCSEC_GSS packet validation
Each RPCSEC_GSS data packet is validated by a routine which checks a signature in the packet. This routine copies a portion of the packet into a stack buffer, but fails to ensure that the buffer is sufficiently large, and a malicious client can trigger a stac…

High 7.2CVE-2025-14558 Public exploit
Remote code execution via ND6 Router Advertisements
The rtsol(8) and rtsold(8) programs do not validate the domain search list options provided in router advertisement messages; the option body is passed to resolvconf(8) unmodified. resolvconf(8) is a shell script which does not validate its input. A lack of q…

Medium 6.5CVE-2022-23093 Public exploit
Stack overflow in ping(8)
ping reads raw IP packets from the network to process responses in the pr_pack() function. As part of processing a response ping has to reconstruct the IP header, the ICMP header and if present a "quoted packet," which represents the packet that generated an …
