CVE-2026-46182

A flaw was found in the Linux kernel, specifically within the pseries/papr-hvpipe module. This vulnerability could allow a local user to gain access to uninitialized kernel stack memory. The issue arises because certain padding bytes in a data structure are not cleared before being sent to...

CVE-2026-46180

A flaw was found in the Linux kernel. A use-after-free vulnerability exists in the brcmfmac Wi-Fi driver when stopping the watchdog task. This issue occurs because the watchdog task might terminate prematurely, leading to a use-after-free condition. This could allow a local attacker to cause a...

CVE-2026-46174

A flaw was found in the Linux kernel, specifically within the x86/CPU/AMD Zen2's op cache. This vulnerability arises from improper isolation of shared resources, which can lead to instruction corruption. The consequence of this flaw is that it may cause unexpected behavior or instability within t...

CVE-2026-46188

A flaw was found in the Linux kernel. Specifically, within the octeonepvf driver, the octepvfoqprocessrx function fails to check for a NULL return value from napibuildskb during memory allocation. This oversight can lead to a NULL pointer dereference, allowing a local attacker to potentially caus...

CVE-2026-46186

A flaw was found in the Linux kernel's virtiobt Bluetooth virtual device driver. An untrusted backend can exploit this vulnerability by sending malformed Bluetooth packets with an insufficient header length. This can cause the system to read uninitialized kernel memory, potentially leading to...

CVE-2026-46166

A flaw was found in the Linux kernel's mac80211 wireless subsystem. This vulnerability arises from unsafe list iteration during radar detection work, where a channel context can be freed while still being processed. This can lead to a use-after-free memory error. A successful exploit could result...

CVE-2026-46176

A flaw was found in the Linux kernel's RDMA/mlx5 component. An error path fall-through in the mlx5ibdevressrqinit function, specifically when ibcreatesrq fails, can lead to the use of freed memory and error pointers. This memory corruption vulnerability could result in system instability, denial ...

CVE-2026-46193

A flaw was found in the Linux kernel's xfrm: ah component, which handles network security protocols. When Extended Sequence Number ESN is active, the kernel incorrectly processes parts of network packet data during security checks. This error can lead to the system dropping legitimate network...

CVE-2026-46189

A flaw was found in the Linux kernel, specifically within the RDMA Remote Direct Memory Access vmwpvrdma module. This vulnerability is a double free, which means the system attempts to release the same memory resource twice. This can occur in an error handling path within the pvrdmaallocucontext...

CVE-2026-46195

A flaw was found in the Linux kernel's Server Message Block SMB client. A malicious server can exploit this vulnerability on 32-bit systems by providing a crafted dacloffset value. This can cause a pointer wrap, leading to the dereferencing of invalid Discretionary Access Control List DACL fields...

About Elevation of Privilege - Linux Kernel "Fragnesia" (CVE-2026-46300) vulnerability

About Elevation of Privilege - Linux Kernel "Fragnesia" CVE-2026-46300 vulnerability. The vulnerability was discovered by researcher William Bowling together with the V12 team. Fragnesia belongs to the class of Dirty Frag vulnerabilities. It is an error in the ESP/XFRM subsystem, distinct from...

CVE-2026-46207

A flaw was found in the Linux kernel's vsock/virtio component. When processing non-linear data buffers for the vsockmon tap device, the system did not correctly initialize the payload. This oversight could lead to uninitialized data being copied to the monitoring interface, potentially resulting ...

kernel: Bluetooth: MGMT: Fix possible UAFs

A flaw was found in the Linux kernel’s Bluetooth management subsystem net/bluetooth/mgmt.c. The mgmtpending structure may be freed while still being processed, or remain on the pending command list, which allows a use-after-free or double-free scenario. An attacker with local access to the system...

kernel: Linux kernel: Denial of service and memory corruption in RDMA umad

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA umad User Mode Access Device component. A local user can exploit this vulnerability by manipulating input, causing an integer underflow that leads to an out-of-bounds memory write. This memory corruption can result in a denia...

kernel: Linux kernel: Use-after-free in traffic control (act_ct) may lead to denial of service or privilege escalation

A flaw was found in the Linux kernel. A use-after-free vulnerability exists in the traffic control actct path when it is incorrectly configured with non-ingress egress qdiscs queueing disciplines. This can allow a local user with specific privileges to trigger a kernel crash, leading to a denial ...

kernel: Bluetooth: SCO: Fix use-after-free in sco_recv_frame() due to missing sock_hold

A flaw was found in the Linux kernel's Bluetooth SCO Synchronous Connection-Oriented protocol implementation. The scorecvframe function fails to properly hold a reference to a socket after releasing a lock. This oversight allows a concurrent operation to free the socket while it is still being...

kernel: md/bitmap: fix GPF in write_page caused by resize race

A flaw was found in the Linux kernel's md/bitmap component. This vulnerability involves a use-after-free race condition that occurs during array resize operations. When the bitmapdaemonwork and bitmapresize functions execute concurrently, they can access memory pages that have already been freed...
