CVE-2026-52963

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Bound MIDI endpoint descriptor scans sndusbmidigetmsinfo validates the internal MIDIStreaming endpoint descriptor size before using baAssocJackID, but the descriptor walker can still return a class-specific...

CVE-2026-52972

In the Linux kernel, the following vulnerability has been resolved: crypto: afalg - Cap AEAD AD length to 0x80000000 In order to prevent arithmetic overflows when checking the TX buffer size, cap the associated data length to 0x80000000...

CVE-2026-52956

In the Linux kernel, the following vulnerability has been resolved: libceph: Fix potential out-of-bounds access in cephxdecrypt In cephxdecrypt, a part of the buffer p is interpreted as a cephxencryptheader, and the magic field of this struct is accessed. This happens without any guarantee that t...

CVE-2026-53091

The CVE-2026-53091 issue concerns the Linux kernel’s handling of GSO packet headers during qdisc_pkt_len_segs_init(). The root cause is that many ndo_start_xmit() paths assume headers are already in skb->head, while tso_build_hdr() may copy from skb->data, and qdisc_pkt_len_segs_init() diss...

CVE-2026-53091 net: pull headers in qdisc_pkt_len_segs_init()

In the Linux kernel, the following vulnerability has been resolved: net: pull headers in qdiscpktlensegsinit Most ndostartxmit methods expects headers of gso packets to be already in skb-head. net/core/tso.c users are particularly at risk, because tsobuildhdr does a memcpyhdr, skb-data, hdrlen;...

CVE-2026-53074

The CVE-2026-53074 issue affects the Linux kernel BPF test path: bpf_prog_test_run_skb may access IPv4/IPv6 headers (ip_hdr/ipv6_hdr) after eth_type_trans() when the test input only contains an Ethernet header. The fix folds IPv4/IPv6 header length checks into the existing protocol switch and ret...

CVE-2026-53029

CVE-2026-53029 affects the Linux kernel ntfs3 filesystem. A vulnerability arises from an uninitialized local variable lcn when handling zero-length data during I/O, which could lead to unpredictable behavior and potential information disclosure or DoS. The fix moves the check for a zero value in ...

CVE-2026-53002

The CVE-2026-53002 entry documents a vulnerability in the Linux kernel’s netfilter/conntrack code. Root cause: use of sprintf with inadequate buffer handling in mangle_content_len(), leading to a potential stack-out-of-bounds write (KASAN). The fix replaces sprintf with scnprintf and increases th...

CVE-2026-53002 netfilter: conntrack: remove sprintf usage

In the Linux kernel, the following vulnerability has been resolved: netfilter: conntrack: remove sprintf usage Replace it with scnprintf, the buffer sizes are expected to be large enough to hold the result, no need for snprintf+overflow check. Increase buffer size in manglecontentlen while at it...

CVE-2026-52994

The CVE-2026-52994 vulnerability affects the Linux kernel’s vsock/virtio code, where the MSG_ZEROCOPY pinned-pages accounting could bypass RLIMIT_MEMLOCK on the last skb due to iter->count being consumed earlier. The fix makes pkt_len (the total bytes sent) the parameter to virtio_transport_in...
