CVE-2026-74598

A flaw was found in the Linux kernel's IPv6 networking stack. An off-by-one error in the validation of the Route Information option length RFC 4191 allows a remote attacker to craft a Router Advertisement RA packet. This crafted packet can cause the kernel to read up to 8 bytes beyond the intende...

CVE-2026-74598

CVE-2026-74598 is an out-of-bounds read in the Linux kernel's IPv6 stack, specifically in rt6_route_rcv() handling of the Route Information option (RFC 4191). Both length checks are off by one: the code accepts length >= 2 and length >= 1 where RFC 4191 requires stricter bounds. A remote at...

CVE-2026-68767 hashcat through 7.1.2 Off-by-One Out-of-Bounds Heap Write in fgetl()

hashcat's fgetl function in src/filehandling.c writes a null terminator one byte past the caller's buffer when an input line is exactly the buffer length. Attackers can trigger this out-of-bounds heap write by providing a hash file, potfile, or wordlist containing a line of exactly HCBUFSIZLARGE...
