CVE-2026-80710

CVE-2026-80710 affects the s390/dasd subsystem of the Linux kernel. In dasd_eckd_check_device_format(), the variable fmt_buffer_size is declared as a 32-bit int, but the expression trkcount * rpt_max * sizeof(struct eckd_count) is evaluated at 64-bit width. When the track range (controlled by cal...

CVE-2026-80634 netfilter: flowtable: avoid num_encaps underflow on bridge VLAN untag

In the Linux kernel, the following vulnerability has been resolved: netfilter: flowtable: avoid numencaps underflow on bridge VLAN untag The DEVPATHBRVLANUNTAG case post-decrements info-numencaps inside WARNONONCE. numencaps is u8, so if it's already 0 the decrement still happens and wraps it to...

CVE-2026-80634

CVE-2026-80634 is a Linux kernel vulnerability in the netfilter flowtable subsystem. The root cause is an integer underflow: in the DEV_PATH_BR_VLAN_UNTAG path, info->num_encaps (a u8) is post-decremented inside WARN_ON_ONCE(), wrapping to 255 when already zero. This causes nft_dev_forward_pat...
