kernel: posix-cpu-timers: Prevent UAF caused by non-leader exec() race
A flaw was found in the Linux kernel's CPU timer functionality. A race condition, which is a timing issue between different operations, can occur when a process attempts to delete a timer while another operation is still trying to access it. This can lead to a Use-After-Free UAF vulnerability,...
kernel: smb: client: mask server-provided mode to 07777 in modefromsid
A flaw was found in the Linux kernel's Server Message Block SMB client. When processing server-provided file mode information, the system incorrectly applies these modes without proper security masking. This can result in unintended file permissions, potentially allowing unauthorized access to...
kernel: ip6_gre: Use cached t->net in ip6erspan_changelink()
A flaw was found in the Linux kernel's ip6gre module. An unprivileged user could exploit this vulnerability by migrating a network device, causing the ip6erspanchangelink function to incorrectly handle network namespace references. This error leads to a use-after-free condition when the original...
kernel: drm/amdgpu: zero-initialize GART table on allocation
A flaw was found in the Linux kernel's AMD GPU amdgpu driver. When allocating a Graphics Address Remapping Table GART, the memory was not properly initialized. This could allow a local attacker to potentially access uninitialized memory, leading to information disclosure or unexpected system...
kernel: scsi: target: iscsi: Fix CRC overread and double-free in iscsit_handle_text_cmd()
A flaw was found in the Linux kernel's iSCSI Internet Small Computer System Interface target subsystem. This vulnerability involves a buffer overread and a double-free error when processing iSCSI Text commands. A remote attacker could exploit these issues by sending specially crafted network...
kernel: netfilter: synproxy: refresh tcphdr after skb_ensure_writable
A flaw was found in the Linux kernel's netfilter synproxy module. When handling TCP timestamp options, a stale pointer can be used after memory reallocation. This can result in memory corruption, where data is written to a freed memory area, or lead to packets being sent with an incorrect checksu...
kernel: smb: client: mask server-provided mode to 07777 in modefromsid
A flaw was found in the Linux kernel's Server Message Block SMB client. When processing server-provided file mode information, the system incorrectly applies these modes without proper security masking. This can result in unintended file permissions, potentially allowing unauthorized access to...
kernel: smb/client: handle overlapping allocated ranges in fallocate
A flaw was found in the Linux kernel's Server Message Block SMB client. The smb3simplefallocaterange function, which manages file allocation, can incorrectly process overlapping allocated ranges provided by a server. This can result in parts of a file not being properly zero-filled, leading to...
kernel: drm/amd/display: Validate payload length and link_index in dc_process_dmub_aux_transfer_async
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Validate payload length and linkindex in dcprocessdmubauxtransferasync Why&How dcprocessdmubauxtransferasync copies payload-length bytes into a 16-byte stack buffer dpaux.data16 guarded only by an ASSERT, which i...
kernel: blk-mq: pop cached request if it is usable
A flaw was found in the Linux kernel's blk-mq component. This use-after-free vulnerability occurs when a task attempts to submit a bio a data structure for I/O operations to blk-mq. If the task is interrupted and sleeps after checking for a cached request but before using it, the cached request c...
kernel: smb/client: fix out-of-bounds read in symlink_data()
A flaw was found in the Linux kernel's Server Message Block SMB client. This vulnerability arises from insufficient length validation in the smb2checkmessage function when processing symlink error responses. A remote attacker could exploit this by sending a specially crafted symlink error respons...
kernel: smb: client: fix query_info() replay double-free
A flaw was found in the Linux kernel's Server Message Block SMB client. This vulnerability, a double-free error, occurs when the queryinfo replay mechanism attempts to free a response buffer that has already been released. This can happen if an error occurs during the initialization of an SMB2...
kernel: crypto: pcrypt - Fix handling of MAY_BACKLOG requests
A flaw was found in the Linux kernel's pcrypt component. This vulnerability involves how the system handles certain requests, specifically MAYBACKLOG requests, which can indicate a temporary busy state. If not properly managed, the system's processing of these requests could lead to resource...
kernel: drm/amdgpu: Refactor amdgpu_gem_va_ioctl for Handling Last Fence Update and Timeline Management v4
A flaw was found in the Linux kernel's AMD GPU amdgpu driver. Incorrect management of graphics memory dmafence references within the amdgpugemvaioctl function can lead to a reference count underflow and a use-after-after-free condition. A local attacker could exploit this vulnerability to trigger...
kernel: drm/amdkfd: Fix watch_id bounds checking in debug address watch v2
A flaw was found in the Linux kernel's AMD KFD Kernel Fusion Driver component. A local user could exploit a boundary error in the debug address watch v2 functionality by providing a specially crafted watchid. This could lead to a buffer overflow, potentially allowing memory access outside of...
kernel: scsi: target: iscsi: Validate CHAP_R length before base64 decode
A flaw was found in the Linux kernel's iSCSI target functionality. This vulnerability allows a remote attacker to cause a buffer overflow by sending a specially crafted Challenge-Handshake Authentication Authentication Protocol CHAP response. The system fails to validate the length of the...
kernel: drm/amdkfd: Fix out-of-bounds write in kfd_event_page_set()
A flaw was found in the Linux kernel's drm/amdkfd component. An unprivileged local user can exploit an out-of-bounds write vulnerability in the kfdeventpageset function. This occurs because the function writes data without properly validating the buffer size, allowing a small buffer to trigger a...
kernel: drm/amd/display: Use krealloc_array() in dal_vector_reserve()
A flaw was found in the Linux kernel's drm/amd/display component. The dalvectorreserve function calculates memory allocation size using 32-bit arithmetic, which can lead to an integer overflow. This overflow causes a smaller memory buffer to be allocated than intended, resulting in a heap overflo...
kernel: drm/i915: Fix potential UAF in TTM object purge
A flaw was found in the Linux kernel's Intel i915 graphics driver drm/i915. This use-after-free UAF vulnerability occurs during the TTM object purge operation. An attacker could potentially exploit this to cause a system crash, leading to a denial of service...
kernel: drm/amdgpu: fix amdgpu_hmm_range_get_pages
A flaw was found in the Linux kernel, specifically within the drm/amdgpu component. This vulnerability arises from incorrect handling of a notifier sequence in the amdgpuhmmrangegetpages function, where the sequence can be read more than once. This can lead to the system processing invalid memory...
