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/i915/gem: Fix phys BO pread/pwrite with offset
A flaw was found in the Linux kernel's drm/i915/gem component. This vulnerability occurs because the sgpage function incorrectly scales pread/pwrite operations for physical Buffer Objects BO when a non-zero offset is used. This can lead to incorrect memory access, potentially allowing an attacker...
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: udf: fix partition descriptor append bookkeeping
A flaw was found in the Linux kernel's Universal Disk Format UDF filesystem. A remote attacker could exploit this vulnerability by tricking a user into mounting a specially crafted UDF image containing repeated partition descriptors. This could lead to a heap out-of-bounds write, potentially...
kernel: drm/amd/display: Clamp VBIOS HDMI retimer register count to array size
A flaw was found in the Linux kernel's AMD display driver. This vulnerability occurs when the driver processes malformed VBIOS Video Basic Input/Output System data. Specifically, unvalidated register counts in the VBIOS can lead to an out-of-bounds memory write during the driver's initialization...
kernel: memfd: deny writeable mappings when implying SEAL_WRITE
A flaw was found in the Linux kernel's memfd component. When the SEALEXEC flag is used to create a memory file descriptor, the SEALWRITE flag is implicitly applied to prevent writing to executable memory. However, this implicit write protection is applied after checks that should deny writable...
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: net: ieee802154: do not leave a dangling sk pointer in ieee802154_create()
A user-after-free vulnerability was found in the linux kernel. sockinitdata attaches the allocated sk object to the provided sock object. If ieee802154create fails later, the allocated sk object is freed, but the dangling pointer remains in the provided sock object, leading to a crash and loss of...
kernel: sched/psi: fix race between file release and pressure write
A flaw was found in the Linux kernel's Pressure Stall Information PSI subsystem. A race condition exists between the file release and pressure write operations, specifically concerning the priv member of struct kernfsopenfile. This can lead to a use-after-free vulnerability or a NULL dereference,...
kernel: scsi: target: iscsi: Bound iscsi_encode_text_output() appends to rsp_buf
A flaw was found in the Linux kernel's iSCSI Internet Small Computer System Interface target functionality. This vulnerability, a heap overrun, occurs because the iscsiencodetextoutput function does not properly check buffer capacity when processing login requests. A remote attacker could exploit...
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: net/smc: reject CHID-0 ACCEPT that matches an empty ism_dev slot
A flaw was found in the Linux kernel's Server-Message-Block Direct SMC-D client. A remote attacker can exploit this vulnerability by sending a specially crafted SMC-Dv2 proposal with a Channel Identifier CHID of 0. This malicious proposal can cause a null pointer dereference in the kernel's SMC...
Important: Red Hat Security Advisory: kernel security, bug fix, and enhancement update
An update for kernel is now available for Red Hat Enterprise Linux 8. 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: 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: 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: mm/huge_memory: update file PMD counter before folio_put()
A flaw was found in the Linux kernel's memory management, specifically within the huge page mechanism. When a huge page is split, the system updates a counter after releasing a reference to the memory. This timing issue can lead to the system attempting to read from memory that has already been...

A flaw was found in the Linux kernel's iSCSI Internet Small Computer System Interface target functionality. This vulnerability, a heap overrun, occurs because the iscsiencodetextoutput function does not properly check buffer capacity when processing login requests. A remote attacker could exploit...
