The vulnerability of the LcpDecodeConfig() function in the operating system kernel of FreeBSD allows a hacker to trigger a service failure or execute arbitrary code.

The vulnerability of the LcpDecodeConfig function in the kernel of the FreeBSD operating system is related to improper handling of discrepancies in parameter length. Exploiting this vulnerability can allow a remote attacker to cause service failures or execute arbitrary code...

CVE-2026-58096

LcpDecodeConfig did not validate the length of received endpoint discriminator options against the minimum required by RFC 1717. Undersized options would trigger an out-of-bounds write. A malicious PPP peer can exploit CVE-2026-58095 and CVE-2026-58096 to crash ppp8 or potentially execute arbitra...

CVE-2026-58096 ppp(8): missing length validation in LcpDecodeConfig()

LcpDecodeConfig did not validate the length of received endpoint discriminator options against the minimum required by RFC 1717. Undersized options would trigger an out-of-bounds write. A malicious PPP peer can exploit CVE-2026-58095 and CVE-2026-58096 to crash ppp8 or potentially execute arbitra...

CVE-2026-58096

The ppp(8) utility in the FreeBSD operating system kernel contains a memory safety vulnerability in the LcpDecodeConfig() function. The flaw exists because the function fails to validate the length of received endpoint discriminator options against the minimum requirements specified in RFC 1717 ,...
