CVE-2026-74681

In the Linux kernel, the following vulnerability has been resolved: usb: misc: usbio: check ibuflen against rxbuflen in bulk msg ibuflen is the bulk IN receive buffer size, but the EMSGSIZE check in usbiobulkmsg compares it against txbuflen — the bulk OUT endpoint size. Both are taken independent...

In the Linux kernel, the following vulnerability has been resolved: netfilter: ebtnflog: pin the NFLOG backend nflogunregister runs after the per-net teardown so its final RCU grace period also drains readers that obtained the logger from a per-net binding. However, ebtnflog passes an explicit UL...

CVE-2026-74660

CVE-2026-74660 is a use-after-free in the Linux kernel's netfilter: ebt_nflog component. The ebt_nflog module passes an explicit ULOG log type to nf_log_packet() without holding a reference on the nfnetlink_log module, unlike the xt_NFLOG and nft_log frontends. This allows an ebtables nflog rule ...

In the Linux kernel, the following vulnerability has been resolved: mm/damon/lrusort: error out for 10000 activemembp damosquotascore can trigger division by zero if the target value is zero. DAMONLRUSORT lets users set the target value for the hot memory scheme via activemembp parameter. It avoi...

CVE-2026-74645

CVE-2026-74645 is a division-by-zero vulnerability in the Linux kernel's DAMON_LRU_SORT module. When a user sets the active_mem_bp parameter to 10002 , the cold memory scheme's quota goal target value becomes zero, causing damos_quota_score() to trigger a kernel oops (divide error). The fix retur...
