CVE-2026-64552

Summary (CVE-2026-64552) In the Linux kernel virtio-net, receive_big() does a length check against (big_packets_num_skbfrags + 1) * PAGE_SIZE, but a gap remains due to add_recvbuf_big() placing sg[1] after the padded vnet header. A malicious virtio backend can announce a length in that gap, causi...

CVE-2026-64552

In the Linux kernel, the following vulnerability has been resolved: virtio-net: fix len check in receivebig receivebig bounds the device-announced length by bigpacketsnumskbfrags + 1 PAGESIZE. That is still too loose: addrecvbufbig sets sg1 to start at offset sizeofstruct paddedvnethdr into the...

CVE-2026-64546

CVE-2026-64546 is a Linux kernel vulnerability in drm/edid that allows a heap out-of-bounds read in drm_parse_tiled_block() when parsing a crafted EDID tiled block. The root cause is casting a DisplayID block to a struct displayid_tiled_block and reading the fixed layout up to tile->topology_i...

In the Linux kernel, the following vulnerability has been resolved: drm/edid: fix OOB read in drmparsetiledblock drmparsetiledblock casts the DisplayID block to a struct displayidtiledblock and reads the full fixed layout up to tile-topologyid7 without checking block-numbytes. The DisplayID...

CVE-2026-64544

CVE-2026-64544 affects the Linux kernel’s crypto: asymmetric_keys path, specifically pefile_digest_pe_contents. The vulnerability arises when calculating the trailing-data hash length as pelen - (hashed_bytes + certs_size); a crafted PE could make the addition overflow the pelen, causing an unsig...

CVE-2026-64539

Linux kernel Bluetooth EIR code (eir_create_adv_data) has a stack-based OOB write vulnerability when prepending a 3-byte Flags AD to advertising data in a fixed-size 31-byte legacy buffer. If adv_data_len approaches the limit and the Flags structure is not fully accommodated, the code can memcpy ...

CVE-2026-64538 ipv6: Fix null-ptr-deref in fib6_nh_mtu_change().

In the Linux kernel, the following vulnerability has been resolved: ipv6: Fix null-ptr-deref in fib6nhmtuchange. fib6nhmtuchange re-fetches idev via in6devgetarg-dev and dereferences idev-cnf.mtu6 without a NULL check. addrconfifdown clears dev-ip6ptr with RCUINITPOINTER after rt6disableip has...

CVE-2026-59729

CVE-2026-59729 affects Astro versions prior to 7.0.6, where unescaped spread attribute names in renderHTMLElement can lead to XSS in SSR when rendering a native HTMLElement-subclass component. The root cause is an inline attribute loop in renderHTMLElement that interpolates attribute names withou...

Summary: Next.js versions affected include 12.0.0–15.5.20 and 16.0.0–16.2.10. A server-side fetch with a request body can return a cached response body from a different request to the same URL when the request body uses a non-UTF-8 charset, causing confidential data in the POST response to leak t...

OSEC-2026-12 AEAD `decrypt_into` functions writes plaintext before checking the tag

On the generic GCM path, AES.GCM.authenticatedecryptinto as well as Chacha20.authenticatedecryptinto and AES.CCM16.authenticatedecryptinto writes the decrypted plaintext into the caller's destination buffer and only then compares the tag. On a forged tag the function returns false, but the...
