WithSecure products Security breaches
WithSecure products is a line of security software from the Finnish company WithSecure. A security vulnerability exists in WithSecure products that originates from a local elevation of privilege that allows an attacker with administrator privileges to corrupt kernel memory. Affected products and...
kernel: selinux: enable use of both GFP_KERNEL and GFP_ATOMIC in convert_context()
In the Linux kernel, the following vulnerability has been resolved: selinux: enable use of both GFPKERNEL and GFPATOMIC in convertcontext The following warning was triggered on a hardware environment: SELinux: Converting 162 SID table entries... BUG: sleeping function called from invalid context ...
kernel: drm/amdkfd: Fix memory leak in kfd_mem_dmamap_userptr()
In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Fix memory leak in kfdmemdmamapuserptr If the number of pages from the userptr BO differs from the SG BO then the allocated memory for the SG table doesn't get freed before returning -EINVAL, which may lead to a memor...
kernel: net: qrtr: Fix an uninit variable access bug in qrtr_tx_resume()
An uninitialized memory access flaw was found in the Linux kernel's QRTR Qualcomm IPC Router protocol in the transmit resume handling. When processing RESUMETX messages, if the packet size is smaller than the expected control structure, the qrtrtxresume function reads uninitialized memory from th...
kernel: gpiolib: fix memory leak in gpiochip_setup_dev()
In the Linux kernel, the following vulnerability has been resolved: gpiolib: fix memory leak in gpiochipsetupdev Here is a backtrace report about memory leak detected in gpiochipsetupdev: unreferenced object 0xffff88810b406400 size 512: comm "python3", pid 1682, jiffies 4295346908 age 24.090s...

kernel: ASoC: codecs: tx-macro: Fix for KASAN: slab-out-of-bounds
A slab-out-of-bounds read vulnerability was found in the Linux kernel's ASoC tx-macro codec driver. The decimator variable was incorrectly sized at 32 bits, causing regcacheflatread to access memory beyond the allocated slab when reading register cache values during the txmacrodigitalmute...
kernel: io_uring/rw: defer fsnotify calls to task context
A locking context violation was found in the Linux kernel's iouring subsystem. The fsnotify calls were being made directly from kiocb completion context, which can execute in soft or hard IRQ context. This causes lockdep warnings when fsnotify attempts memory allocation with GFPKERNEL flags, whic...
kernel: USB: ULPI: fix memory leak with using debugfs_lookup()
In the Linux kernel, the following vulnerability has been resolved: USB: ULPI: fix memory leak with using debugfslookup When calling debugfslookup the result must have dput called on it, otherwise the memory will leak over time. To make things simpler, just call debugfslookupandremove instead whi...
kernel: drm/amdkfd: Fix memory leak in kfd_mem_dmamap_userptr()
In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Fix memory leak in kfdmemdmamapuserptr If the number of pages from the userptr BO differs from the SG BO then the allocated memory for the SG table doesn't get freed before returning -EINVAL, which may lead to a memor...
kernel: mm/vmemmap/devdax: fix kernel crash when probing devdax devices
A flaw was discovered in the device DAX devdax probing implementation of the Linux kernel memory management subsystem mm/vmemmap/devdax. Under specific architecture configurations for example POWER9 with hash MMU, the code path in vmemmappopulatecompoundpages did not properly account for...
kernel: bpf, verifier: Fix memory leak in array reallocation for stack state
A flaw was found in the eBPF subsystem in the Linux kernel. An incorrect logic in a helper function for memory reallocation can cause memory leaks when a memory allocation error occurs, potentially leading to system instability and a denial of service...
kernel: drm/amdkfd: Fix memory leakage
In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Fix memory leakage This patch fixes potential memory leakage and seg fault in gpuvmimportdmabuf function...
A use-after-free vulnerability was found in the Netfilter subsystem of the Linux kernel when processing batch requests to update nf_tables configuration. (CVE-2023-32233)
In the Linux kernel through 6.3.1, a use-after-free in Netfilter nftables when processing batch requests can be abused to perform arbitrary read and write operations on kernel memory. Unprivileged local users can obtain root privileges. This occurs because anonymous sets are mishandled...

Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: A memory leak issue has been identified in the Linux kernel when using fscache. Specifically, when the 'index == next cached' case is encountered, a refcount leak on the struct page...
Rocky Linux 8 : kernel-rt (RLSA-2022:5344)
The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2022:5344 advisory. - A buffer over-read at the framebuffer layer in the fbcon code in the Linux kernel before 5.8.15 could be used by local attackers to read kernel memory...

The SUSE Linux Enterprise 15 SP4 RT kernel was updated to receive various security and bugfixes. The following security bugs were fixed: - CVE-2023-3777: Fixed a use-after-free vulnerability in netfilter: nftables component can be exploited to achieve local privilege escalation. bsc1215095 -...
Researchers Find 34 Windows Drivers Vulnerable to Full Device Takeover
As many as 34 unique vulnerable Windows Driver Model WDM and Windows Driver Frameworks WDF drivers could be exploited by non-privileged threat actors to gain full control of the devices and execute arbitrary code on the underlying systems. "By exploiting the drivers, an attacker without privilege...
SUSE CVE-2017-2618
A flaw was found in the Linux kernel's handling of clearing SELinux attributes on /proc/pid/attr files before 4.9.10. An empty null write to this file can crash the system by causing the system to attempt to access unmapped kernel memory...
