CVE-2026-97185

A flaw was found in GIMP. When processing a specially crafted GIMPressionist preset file, the plug-in does not properly validate vector indices before writing into fixed-size arrays. This can lead to an out-of-bounds write, corrupting memory. An attacker could exploit this by convincing a user to...

xdgmime: heap-based buffer overflow in _xdg_mime_magic_parse_magic_line() in xdgmimemagic.c

A flaw was found in xdgmime. A heap-based buffer overflow can be triggered in xdgmimemagicparsemagicline in the xdgmimemagic.c file on little-endian systems when an attacker-controlled MIME magic file in a user-writable XDG data location e.g., in the $XDGDATAHOME/mime/magic path is parsed by an...

xdgmime: heap-based buffer overflow in _xdg_mime_magic_parse_magic_line() in xdgmimemagic.c

A flaw was found in xdgmime. A heap-based buffer overflow can be triggered in xdgmimemagicparsemagicline in the xdgmimemagic.c file on little-endian systems when an attacker-controlled MIME magic file in a user-writable XDG data location e.g., in the $XDGDATAHOME/mime/magic path is parsed by an...

encoding/xml: golang: Go: Denial of Service via XML decoding recursion depth issue

A flaw was found in the encoding/xml package of Go. The DecodeElement function failed to correctly track recursion depth, which could lead to stack exhaustion. A remote attacker could exploit this vulnerability by providing a specially crafted XML input, resulting in a Denial of Service DoS for t...

net/url: golang: golang net/url: Denial of Service from quadratic complexity in path resolution

A flaw was found in net/url, a component of golang. This vulnerability arises when resolving relative paths that contain numerous parent directory '..' segments. A remote attacker could exploit this by providing a specially crafted path, leading to quadratic time complexity and excessive memory...

kernel: net: tun: bound receive headroom

A flaw was found in the Linux kernel's TUN/TAP driver. An integer underflow vulnerability exists in the tungetuser function when processing oversized headroom requests. This can occur if Open vSwitch OVS propagates an excessively large headroom request to the TUN or TAP device. Successful...

kernel: block: don't overwrite bip_vcnt in bio_integrity_copy_user()

A flaw was found in the Linux kernel's block integrity subsystem. Incorrect handling of bio integrity vector counts in the biointegritycopyuser function can lead to an out-of-bounds read during write operations. This vulnerability may allow a local attacker to cause a denial of service or...

kernel: scsi: qla2xxx: Bound rsp_info_len to avoid OOB sense-data read

A flaw was found in the Linux kernel's scsi: qla2xxx driver. A remote attacker, by sending a specially crafted Fibre Channel Protocol FCP response, could cause an integer underflow. This underflow leads to an out-of-bounds read when handling sense data, potentially disclosing sensitive memory...

kernel: mac802154: llsec: add skb_cow_data() before in-place crypto

A flaw was found in the Linux kernel's mac802154 IEEE 802.15.4 MAC security component. This vulnerability allows for data corruption and potential kernel crashes when cryptographic transformations are performed on shared network packet data without proper isolation. A remote attacker could exploi...

kernel: ALSA: timer: drain a slave's callback before its master detaches it

A flaw was found in the ALSA Advanced Linux Sound Architecture timer component of the Linux kernel. When a master timer instance is closed, it does not properly ensure that all associated slave timer callbacks have finished executing before detaching them. This oversight can lead to a...

kernel: ASoC: SOF: ipc3-control: Validate size in snd_sof_update_control

A flaw was found in the Linux kernel's Sound Open Firmware SOF subsystem, specifically within the ipc3-control component. This vulnerability occurs in the sndsofupdatecontrol function where the size of firmware-provided data is not properly validated against the allocated buffer size. An attacker...

kernel: block: zero non-PI portion of auto integrity buffer

An information disclosure vulnerability was found in the Linux kernel's block layer integrity handling. When auto-generating integrity buffers for writes with protection information PI enabled, the non-PI portion of the metadata buffer is left uninitialized if the metadata size exceeds the PI tup...

kernel: smb: client: fix double-free in SMB2_flush() replay

A flaw was found in the Linux kernel's Server Message Block SMB client. This vulnerability, a double-free error within the SMB2flush replay mechanism, occurs when the system attempts to free a memory buffer twice. A malicious SMB server could exploit this by sending a specially crafted flush...

kernel: nvmet-tcp: check INIT_FAILED before nvmet_req_uninit in digest error path

A flaw was found in the Linux kernel's NVMe over TCP nvmet-tcp implementation. When a data digest mismatch occurs, a reference count underflow can happen due to an unconditional cleanup call. This issue can lead to a use-after-free condition and ultimately result in a permanent workqueue deadlock...

kernel: blk-cgroup: fix UAF in __blkcg_rstat_flush()

A flaw was found in the Linux kernel's block input/output control group blk-cgroup component. This vulnerability, a Use-After-Free UAF, occurs when multiple block control groups are released at the same time. A race condition allows one group to remove another's entries while it is still in use,...

kernel: sctp: don't free the ASCONF's own transport in DEL-IP processing

A flaw was found in the Stream Control Transmission Protocol SCTP implementation within the Linux kernel. A remote attacker could send a specially crafted sequence of ASCONF Add IP Address Configuration chunks, including DEL-IP Delete IP Address parameters, to trigger a use-after-free condition...

kernel: xfrm: ah6: validate routing header segments_left

A flaw was found in the Linux kernel's xfrm subsystem, specifically within the AH6 Authentication Header for IPv6 module. The ipv6rearrangerthdr function does not properly validate the segmentsleft field in routing headers when processing raw IPv6 HDRINCL packets. This oversight allows an attacke...

kernel: af_unix: Drop all SCM attributes for SOCKMAP

A flaw was found in the Linux kernel's afunix component, specifically within its SOCKMAP feature. This vulnerability stems from the kernel's improper handling of Socket Control Message SCM attributes when data is passed to the SOCKMAP layer. This can lead to a use-after-free condition, which may...

sudo: Sudo: Policy bypass allows unauthorized program execution via execveat

A flaw was found in Sudo. This vulnerability allows users who are permitted to run specific commands to bypass security policy checks when using the execveat system call in ptrace-based intercept mode. By directly calling execveat or fexecve, an attacker can execute programs that would otherwise ...
