kernel: ixgbevf: fix use-after-free in VEPA multicast source pruning

A flaw was found in the Linux kernel's ixgbevf network driver. This vulnerability, a use-after-free, occurs when the driver attempts to process network packets for a specific multicast workaround. An attacker could potentially exploit this by sending specially crafted network traffic, which may...

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...

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: net: pull headers in qdisc_pkt_len_segs_init()

A flaw was found in the Linux kernel's handling of Generic Segmentation Offload GSO packet headers. This vulnerability occurs when the qdiscpktlensegsinit function does not properly pull headers into the expected memory location, which can lead to incorrect processing by network drivers. A remote...

kernel: Bluetooth: ISO: fix UAF in iso_recv_frame

A flaw was found in the Linux kernel's Bluetooth ISO Isochronous Stream subsystem. This vulnerability, known as a Use-After-Free, occurs because the system attempts to use a memory area after it has been released, which can lead to unpredictable behavior. A malicious actor could potentially explo...

kernel: Bluetooth: hci_sync: reject oversized Broadcast Announcement prepend

A flaw was found in the Bluetooth subsystem of the Linux kernel, specifically within the hcisync component. This vulnerability occurs when the hciadvbcastannoucement function attempts to prepend Broadcast Announcement service data to an existing advertising payload that is already at its maximum...

kernel: Bluetooth: L2CAP: Fix possible crash on l2cap_ecred_conn_rsp

A flaw was found in the Bluetooth L2CAP Logical Link Control and Adaptation Protocol component of the Linux kernel. When a device receives a connection response with an already-assigned destination Channel Identifier CID, the system may crash. This occurs because the kernel's procedure for...

Important: Red Hat Security Advisory: kernel security, bug fix, and enhancement update

An update for kernel is now available for Red Hat Enterprise Linux 9. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each vulnerability from th...

kernel: Bluetooth: ISO: serialize iso_sock_clear_timer with socket lock

A flaw was found in the Linux kernel's Bluetooth ISO Isochronous Stream subsystem. A race condition exists where the isosockcleartimer function can access connection data without proper locking, while another function, isoconndel, concurrently modifies the same data. This can lead to a NULL point...

kernel: tipc: fix slab-use-after-free Read in tipc_aead_decrypt_done

A flaw was found in the Linux kernel. A remote attacker could exploit a use-after-free vulnerability in the Transparent Inter-Process Communication TIPC cryptographic decryption process. This flaw occurs when a network namespace, a mechanism for isolating network resources, is deallocated before ...

kernel: wifi: cfg80211: validate PMSR FTM preamble range

A flaw was found in the cfg80211 component of the Linux kernel's Wi-Fi subsystem. This vulnerability allows the PMSR FTM request parser to accept preamble values outside the defined nl80211 range. An attacker could exploit this by providing malformed input, potentially leading to unexpected syste...

kernel: sctp: validate stream count in sctp_process_strreset_inreq()

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. When processing a Stream Reset Incoming Request RESETINREQUEST from a peer, the kernel does not properly validate the stream count. This can lead to an integer overflow when calculating the size for t...

kernel: sctp: fix auth_hmacs array size in struct sctp_cookie

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. An incorrect array size calculation for the authhmacs field within the sctpcookie structure could lead to a buffer overflow. During the initialization of an SCTP association, if four HMAC identifiers...

kernel: iommu/amd: Fix clone_alias() to use the original device's devid

A flaw was found in the Linux kernel's IOMMU Input/Output Memory Management Unit AMD driver. The clonealias function incorrectly uses the device ID devid when handling alias devices. This can lead to the propagation of wrong or stale Device Table Entry DTE entries to alias devices, potentially...

kernel: mm/khugepaged: write all dirty file folios when collapsing

A flaw was found in the Linux kernel's memory management mm/khugepaged component. A local user could trigger an edge case where unsaved changes to file data dirty folios are improperly discarded. This occurs when a file with previous writes is subjected to a specific sequence of memory advice...

kernel: dm-verity: fix buffer overflow in FEC calculation

A flaw was found in the dm-verity component of the Linux kernel. A buffer overflow occurs during Forward Error Correction FEC calculation, allowing an attacker to write past the end of an allocated buffer. This out-of-bounds write can corrupt the syndrome buffer, potentially leading to system...

libkcapi: Memory corruption via uncanceled AIO requests on error in libkcapi's one-shot AIO path

Memory Corruption via Uncanceled AIO Requests on Error: libkcapi's one-shot AIO path can return an error before all submitted IOCBs are drained, allowing later kernel writes into caller-owned output buffers...
