CVE-2026-74640

This is an out-of-bounds write in the Linux kernel's ALSA FCP (FireWire Control Protocol) driver, specifically in fcp_meter_ctl_get(). The root cause is a mismatch: fcp_ioctl_set_meter_map() permits a Level Meter map size up to 255 , but the destination buffer struct snd_ctl_elem_value declares l...

In the Linux kernel, the following vulnerability has been resolved: ip6tunnel: clear skb2-cb in ip6ip6err ip6ip6err clones an outer IPv6 ICMP error skb, pulls it to the quoted inner IPv6 packet, and then passes the clone to icmpv6send. The clone still carries the outer packet's inet6skbparm in...

CVE-2026-68768

hashcat contains a heap-based buffer overflow out-of-bounds write in the outfilewrite function in src/outfile.c. When assembling output into a fixed-size buffer HCBUFSIZLARGE, 16 MB, the function sequentially appends the username, separator, hash, and plaintext via memcpy without validating that...

CVE-2026-68767

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...
