CVE-2026-74282

In the Linux kernel vulnerability CVE-2026-74282, the TIPC stack allows an oversized CONN_ACK to cause snt_unacked to underflow. The root cause is tipc_sk_conn_proto_rcv() subtracting the peer-supplied ack count from an unsigned 16-bit snt_unacked without ensuring it does not exceed the outstandi...

CVE-2026-74269

CVE-2026-74269 describes a Linux kernel issue where bnxt RX path under XDP head-grow can underflow the skb head when the head is adjusted by -256. The root cause is an underflow in bnxt_rx_multi_page_skb that builds the skb with napi_build_skb(data_ptr - bp->rx_offset, rxr->rx_page_size); b...

CVE-2026-74256

The CVE-2026-74256 family affects the Linux kernel’s BPF sockmap path, where bpf_msg_pop_data() bounds checks used 32-bit arithmetic on start/len. An unsigned-to-signed overflow could allow an out-of-range start/len, causing the pop loop to walk past scatterlist end and trigger put_page on an emp...

CVE-2026-72382

CVE-2026-72382 affects the Linux kernel ksmbd component. The issue is an unsigned underflow in parse_dacl() when computing the ACE count for a security descriptor, caused by subtracting sizeof(struct smb_acl) from a 16-bit DACL size. This can allow a malformed security descriptor to bypass the AC...

CVE-2026-72369

CVE-2026-72369 (Minix) - detail summary : The Linux kernel vulnerability arises in minix_check_superblock() where minix_blocks_needed() uses unsigned DIV_ROUND_UP(), allowing s_ninodes/s_zones near UINT_MAX to wrap to zero, making a zero bitmap-block count appear valid. This can lead to dereferen...
