kernel: drm/xe/pt: Reset current_op in xe_pt_update_ops_init()

A flaw was found in the Linux kernel's drm/xe/pt module. During certain memory management operations, an internal counter is not properly reset. Repeated attempts to perform these operations, possibly due to resource contention or out-of-memory conditions, can cause this counter to exceed its...

kernel: xfrm: input: hold netns during deferred transport reinjection

A flaw was found in the Linux kernel's xfrm input component. The transport-mode reinjection process, which handles network packet re-injection, stores a network namespace pointer that must remain valid until a deferred callback completes. However, a missing reference count for the network namespa...

kernel: lsm: hold cred_guard_mutex for lsm_set_self_attr()

A flaw was found in the Linux kernel's Security Module LSM. A local attacker could exploit this vulnerability by leveraging an improper handling of a credential guard mutex in the lsmsetselfattr function. This oversight may allow the attacker to bypass security restrictions enforced by modules su...

kernel: drm/amdgpu: Fix use-after-free race in VM acquire

A flaw was found in the Linux kernel's AMD GPU amdgpu driver. This vulnerability involves a timing issue, known as a race condition, during the process of acquiring a Virtual Machine VM. When multiple processes attempt to access the same VM simultaneously, a local attacker could exploit this flaw...

kernel: vhost: move vdpa group bound check to vhost_vdpa

A flaw was found in the Linux kernel's vhost subsystem. Specifically, a bug in the vdpasim component allows for an out-of-bounds write when a valid ASID Address Space ID is incorrectly assigned to a vDPA virtio Data Path Acceleration group. This could lead to memory corruption, potentially...

kernel: xfrm: hold dev ref until after transport_finish NF_HOOK

A flaw was found in the Linux kernel's xfrm IP eXtensible FRamework subsystem. This vulnerability involves a race condition where a network device's reference is released too early during packet processing after asynchronous cryptography. This premature release can lead to the system attempting t...

kernel: drm/xe: Open-code GGTT MMIO access protection

A flaw was found in the drm/xe component of the Linux kernel. This vulnerability involves insufficient protection of Graphics Translation Table GGTT Memory-Mapped I/O MMIO access. When the driver fails to load or during certain cleanup operations, the system's memory access protection is...

kernel: xfrm: policy: fix use-after-free on inexact bin in xfrm_policy_bysel_ctx()

A flaw was found in the Linux kernel. A race condition exists in the xfrm policy handling, specifically within the xfrmpolicybyselctx function. This flaw allows for a use-after-free vulnerability, where memory is accessed after it has been released. This can lead to system instability or a denial...

kernel: sctp: validate cached peer INIT chunk length in COOKIE_ECHO processing

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. A remote attacker could exploit this by sending a specially crafted COOKIEECHO chunk to a listening SCTP server. The server's failure to properly validate the length of a cached peer INIT chunk within...

kernel: netfilter: require Ethernet MAC header before using eth_hdr()

A flaw was found in the Linux kernel's netfilter component. Certain netfilter modules, including ip6teui64 and xtmac, accessed Ethernet MAC header data without first verifying that an Ethernet device was associated with the network packet or that the MAC header was present and of sufficient lengt...

kernel: drm/amdgpu: Fix fence put before wait in amdgpu_amdkfd_submit_ib

A flaw was found in the Linux kernel's AMD GPU amdgpu driver. An issue in the amdgpuamdkfdsubmitib function allows a local user to trigger a use-after-free vulnerability. This occurs because a fence reference is incorrectly released before waiting for job completion, potentially freeing the memor...

kernel: drm/i915/gt: fix refcount underflow in intel_engine_park_heartbeat

A flaw was found in the Linux kernel's i915 graphics driver. A race condition exists between the heartbeat worker and intelengineparkheartbeat functions when releasing an engine request. This can lead to a reference count refcount underflow, resulting in a use-after-free vulnerability. A local...

kernel: smb: smbdirect: introduce smbdirect_socket.recv_io.credits.available

A flaw was found in the Linux kernel's smbdirect module. A race condition in the receive credit management logic allows the system to grant credits that a peer has already consumed. This timing vulnerability, occurring during the processing of incoming data, could lead to resource exhaustion and...

kernel: drm/i915: Fix potential overflow of shmem scatterlist length

A flaw was found in the Linux kernel's graphics memory management drm/i915 component. This vulnerability occurs when a large shared memory object's internal list of memory segments, called a scatterlist, is populated. If the total size of these segments exceeds 4 Gigabytes GB, a numerical overflo...

kernel: drm/xe: always keep track of remap prev/next

A flaw was found in the Linux kernel's drm/xe driver. During 3D workload processing, a user process can trigger an issue in the Virtual Memory Area VMA management when performing a rebind operation. This can lead to an invalid or overlapping VMA insertion, causing the system to enter an unstable...

kernel: scsi: libiscsi_tcp: Bound SCSI Response data segment to the connection buffer

A flaw was found in the Linux kernel's libiscsitcp component. A remote attacker, acting as a malicious iSCSI target, could send a specially crafted iSCSI SCSI Command Response ISCSIOPSCSICMDRSP with an oversized data segment. This could lead to a buffer overflow in a fixed-size buffer, potentiall...

kernel: scsi: scsi_transport_fc: Widen FPIN pname walker counter to u32

A flaw was found in the Linux kernel's Fibre Channel FC transport component. An adjacent Fibre Channel fabric actor, such as a compromised switch or fabric controller, can send a specially crafted FPIN ELS Fabric Performance Incentive Notification Extended Link Service frame. This malformed frame...

kernel: ip6: vti: Use ip6_tnl.net in vti6_siocdevprivate()

A flaw was found in the Linux kernel's IPv6 Virtual Tunnel Interface VTI module. When a VTI tunnel device is moved to a different network environment, an unprivileged user in a separate user space can manipulate tunnel parameters. This manipulation could allow the user to intercept or redirect...

kernel: Linux kernel: Denial of Service in qla2xxx SCSI driver due to improper command handling after chip reset

A flaw was found in the Linux kernel's qla2xxx SCSI driver. This vulnerability occurs when commands sent to the firmware FW are not properly cleared after a chip reset. A local attacker could exploit a race condition during direct memory access DMA unmapping, leading to a kernel panic. This can...
