CVE-2026-93191

A flaw was found in the Linux kernel's SMACK Simplified Mandatory Access Control Kernel module. The smackmsgqueuemsgrcv function incorrectly checks the permissions of the sending task instead of the receiving task when using a message queue. This allows an unauthorized local user, operating under...

CVE-2026-93190

A flaw was found in the crosectypec component of the Linux kernel. The crostypecregisterpartnerpdos function does not properly validate the sourcecapcount and sinkcapcount values received from the Embedded Controller EC. An attacker could potentially provide manipulated count values, leading to a...

CVE-2026-93189

A flaw was found in the Linux kernel's Human Interface Device HID core. When a driver's probe fails after enabling input delivery, the hidhwstop function may free a hidraw structure while in-flight HID reports are still being processed. This timing issue can lead to a use-after-free vulnerability...

CVE-2026-93188

A flaw was found in the Linux kernel's Roccat Human Interface Device HID driver. A local attacker, by connecting a specially crafted malicious USB device, can send an out-of-range profile index. This can lead to an out-of-bounds read, resulting in the disclosure of sensitive information through t...

CVE-2026-93187

A flaw was found in the Linux kernel's Sound Open Firmware SOF IPC4 topology component. When internal functions sofipc4widgetsetupcompsrc and sofipc4widgetsetupcompasrc are invoked with an invalid number of input or output formats specifically, zero, they incorrectly report a successful operation...

CVE-2026-90349

A flaw was found in the Linux kernel's mt76 wireless driver, specifically within the mt7996tx function. When the mac80211 subsystem leaves the link unspecified, the driver substitutes a primary link ID that is then used without proper bounds checking to access internal arrays. This unchecked acce...

CVE-2026-90347

A flaw was found in the Linux kernel. On ARM64 architectures, a vulnerability in the ptrace system call entry tracing mechanism allows a local attacker to manipulate the first system call argument. This manipulation can occur without being subjected to security checks, such as seccomp or audit...

CVE-2026-90344

A flaw was found in the Linux kernel's mac80211 wireless subsystem. A remote attacker, operating a malicious Access Point AP, could exploit this by sending a Channel Switch Announcement CSA to an invalid channel, specifically channel zero. Due to an error in parsing the CSA, the system fails to...

CVE-2026-90343

A flaw was found in the Linux kernel's Wi-Fi Wireless Fidelity subsystem, specifically within the cfg80211 component. When a Wi-Fi Peer-to-Peer P2P device or Neighborhood Area Network NAN interface is stopped while a Passive Measurement Scan Request PMSR is pending, the driver may retain a stale...

CVE-2026-90342

A flaw was found in the Linux kernel. A local user could potentially trigger a deadlock within the kernel's memory management, specifically related to the mmaplock mechanism. This issue arises when the arenavmfault function attempts to retry a memory fault without correctly releasing a previously...

CVE-2026-90341

A flaw was found in the Linux kernel's handling of coreboot firmware tables. A local attacker with control over firmware could provide a malformed coreboot table. This could cause an overflow in size calculations or an advertised extent beyond the allocated resource, leading the kernel to map and...

CVE-2026-90339

A flaw was found in the Linux kernel's powerpc/syscall component. This vulnerability occurs when the systemcallexception function incorrectly handles a sentinel value during syscall processing, particularly when security mechanisms like seccomp or ptrace intercept a syscall. This can lead to an...

CVE-2026-93204

A flaw was found in the batman-adv component of the Linux kernel. When a Media Access Control MAC address is updated, the update is not performed atomically. This allows a parallel process to read a partially updated MAC address, which could then be used to poison the Address Resolution Protocol...

CVE-2026-93203

A flaw was found in the B.A.T.M.A.N. Advanced Better Approach To Mobile Ad-hoc Networking module of the Linux kernel. This vulnerability occurs when the system attempts to add new claims and modify existing claim backbones in parallel. Under specific timing conditions, this parallel processing ca...

CVE-2026-93201

A flaw was found in the Linux kernel's dm-pcache component. An attacker with administrative privileges CAPSYSADMIN can supply a specially crafted cache device with an out-of-range segment identifier. This can lead to an out-of-bounds read and write, resulting in memory corruption and potentially...

CVE-2018-17182

CVE-2018-17182 Linux kernel VMA-UAF privilege escalation vulnerability CVE-2018-17182 About Google Project Zero cybersecurity researchers have released details and a proof-of-concept PoC exploit for a high-severity vulnerability in the Linux kernel that has been present since kernel versions 3.16...

CVE-2024-27815

CVE-2024-27815 XNU kernel heap buffer overflow in sbconcatmbufs bsd/kern/uipcsocket2.c, reachable by an unprivileged local user over the AFUNIX datagram socket layer. A socket address of up to SOCKMAXADDRLEN 255 bytes is copied into an mbuf data area only MLEN 224 bytes long, overwriting up to 31...

CVE-2026-19940 Bluetooth HFP AG reuses a connection slot while a delayable work item is still armed, corrupting kernel timeout bookkeeping

The Bluetooth Classic Hands-Free Profile Audio Gateway implementation in subsys/bluetooth/host/classic/hfpag.c keeps its struct bthfpag objects in a static pool indexed by ACL connection index. On link teardown, hfpagdisconnected cancels ag-txwork and the per-call work items and then clears...

CVE-2026-19940

The Bluetooth Classic Hands-Free Profile Audio Gateway implementation in subsys/bluetooth/host/classic/hfp_ag.c is vulnerable to a memory corruption issue. When a link is torn down, the hfp_ag_disconnected() function fails to cancel the ag->ongoing_call_work item. If a new connection reuses th...
