CVE-2026-68145

In the Linux kernel, the following vulnerability has been resolved: iomap: fix out-of-bounds bitmapset with zero-length range ifssetrangedirty and ifssetrangeuptodate compute lastblk as off + len - 1 iblkbits. When off is 0 and len is 0, the unsigned subtraction underflows to SIZEMAX, producing a...

CVE-2026-68125

In the Linux kernel, the following vulnerability has been resolved: mac802154: llsec: reject frames shorter than the authentication tag llsecdodecryptauth computes the associated-data length for the AEAD request as assoclen += datalen - authlen; where datalen is the number of bytes after the MAC...

CVE-2026-68123

In the Linux kernel, the following vulnerability has been resolved: openvswitch: fix GSO userspace truncation underflow OVSACTIONATTRTRUNC currently stores a delta from the original skb length in OVSCBskb-cutlen. When a later userspace action segments a GSO skb, queuegsopackets reuses that delta...

CVE-2026-68124

In the Linux kernel, the following vulnerability has been resolved: mctp: serial: handle zero-length frames to prevent rx buffer overflow The MCTP serial receive state machine reads a frame length byte in mctpserialpushheader case 2 and validates it upper-bound-only: if c MCTPSERIALFRAMEMTU...

CVE-2026-68107

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/vcn4: avoid rereading IB param length Reuse the parameter length returned by vcnv40encfindibparam instead of rereading it from the IB. This avoids a potential TOCTOU issue if the IB contents change between reads. cherr...

CVE-2026-18370

entr is vulnerable to Heap-based buffer overflow in runutility function. The function allocates a fixed-size heap buffer using mallocARGMAX and copies command-line arguments into it. It advances the destination pointer based on the return value of strlcpy, which returns the total length of the...

CVE-2026-68088

CVE-2026-68412 wifi: cfg80211: Fix an error handling path in cfg80211_wext_siwscan()

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: Fix an error handling path in cfg80211wextsiwscan If the test against IEEE80211MAXSSIDLEN fails, then 'creq' leaks. Use the existing error handling path to fix it...

CVE-2026-68412

The CVE-2026-68412 affects the Linux kernel’s wireless subsystem, specifically the cfg80211_wext_siwscan() error path. If the IEEE80211_MAX_SSID_LEN test fails, the request (creq) could leak due to improper error handling. The fix uses the existing error handling path to prevent the leak. No expl...

CVE-2026-68411

The CVE affects the Linux kernel’s wifi/mac80211_hwsim path. In hwsim_virtio_rx_work(), the virtqueue used-ring length reported by the device could be passed directly to skb_put() on a fixed-size receive skb, allowing skb_over_panic() and a host-triggerable guest panic (DoS) when length exceeds t...

CVE-2026-68411 wifi: mac80211_hwsim: clamp virtio RX length before skb_put

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211hwsim: clamp virtio RX length before skbput hwsimvirtiorxwork passes the virtqueue used-ring length reported by the device straight to skbput on a fixed-size receive skb. A backend reporting a length larger than the...
