In the Linux kernel, the following vulnerability has been resolved: ksmbd: reject undersized DACLs before parsing ACEs parsedacl limits the attacker-controlled ACE count by comparing it with the number of minimal ACEs that fit in the DACL size. The DACL size field is 16 bits, but the expression...

SUSE CVE-2026-72326

In the Linux kernel, the following vulnerability has been resolved: net/sched: cake: reject overhead values that underflow length CAKE accepts signed overhead values and stores them in an s16, but the adjusted packet length calculation uses unsigned arithmetic. A negative effective length can...

CVE-2026-80634

A flaw was found in the Linux kernel's netfilter flowtable component. An integer underflow can occur during bridge Virtual Local Area Network VLAN untagging operations. If the numencaps value is zero, a decrement operation can cause it to wrap to 255. This can lead to an out-of-bounds stack read...

CVE-2026-71401

A flaw was found in wicked, specifically in its DHCPv4 packet capture code. An integer underflow vulnerability exists where the nicaptureinspectudpheader function fails to validate the IP total length field against the IP header length before performing a subtraction. This oversight allows an...
