UBUNTU-CVE-2026-120831
A flaw was found in libslirp in ifoutput. When moving a session from the fast queue to the batch queue, the code unlinked and reinserted an arbitrary packet via ifm-mnextpkt instead of the session queue head, corrupting queue pointers. A guest generating burst traffic could crash the host...
UBUNTU-CVE-2026-120830
A flaw was found in libslirp in icmpforwarderror. When building an ICMP error response, the length of the quoted original IPv4 packet was taken from the IP header without clamping it to the actual buffer length. A truncated or malformed packet could cause an out-of-bounds heap read, leaking host...
