Tenda AX1803 v1.0.0.1 was discovered to contain a stack overflow via the function fromSetIpMacBind.

In the Linux kernel, the following vulnerability has been resolved: fbdev: sisfb: Fix strbuf array overflow The values of the variables xres and yres are placed in strbuf. These variables are obtained from strbuf1. The strbuf1 array contains digit characters and a space if the array contains non-digit characters. Then, when executing sprintf(strbuf, "%ux%ux8", xres, yres); more than 16 bytes will be written to strbuf. It is suggested to increase the size of the strbuf array to 24. Found by Linux Verification Center (linuxtesting.org) with SVACE.

A heap-based overflow vulnerability in GetCorrectDbLanguageTypeEsPKc function in libSDKRecognitionText.spensdk.samsung.so library prior to SMR Sep-2022 Release 1 allows attacker to cause memory access fault.

A flaw was found in the HFS filesystem. When reading an HFS volume's name at grub_fs_mount(), the HFS filesystem driver performs a strcpy() using the user-provided volume name as input without properly validating the volume name's length. This issue may read to a heap-based out-of-bounds writer, impacting grub's sensitive data integrity and eventually leading to a secure boot protection bypass.

Windows Common Log File System Driver Elevation of Privilege Vulnerability

In the Linux kernel, the following vulnerability has been resolved: bpf, arm64: Fix address emission with tag-based KASAN enabled When BPF_TRAMP_F_CALL_ORIG is enabled, the address of a bpf_tramp_image struct on the stack is passed during the size calculation pass and an address on the heap is passed during code generation. This may cause a heap buffer overflow if the heap address is tagged because emit_a64_mov_i64() will emit longer code than it did during the size calculation pass. The same problem could occur without tag-based KASAN if one of the 16-bit words of the stack address happened to be all-ones during the size calculation pass. Fix the problem by assuming the worst case (4 instructions) when calculating the size of the bpf_tramp_image address emission.

A privilege escalation vulnerability was reported in the Lenovo HardwareScanPlugin prior to version 1.3.1.2 and Lenovo Diagnostics prior to version 4.45 that could allow a local user to execute code with elevated privileges.

Memory corruption can occur if an already verified IFS2 image is overwritten, bypassing boot verification. This allows unauthorized programs to be injected into security-sensitive images, enabling the booting of a tampered IFS2 system image.

In the Linux kernel, the following vulnerability has been resolved: s390/dasd: fix error recovery leading to data corruption on ESE devices Extent Space Efficient (ESE) or thin provisioned volumes need to be formatted on demand during usual IO processing. The dasd_ese_needs_format function checks for error codes that signal the non existence of a proper track format. The check for incorrect length is to imprecise since other error cases leading to transport of insufficient data also have this flag set. This might lead to data corruption in certain error cases for example during a storage server warmstart. Fix by removing the check for incorrect length and replacing by explicitly checking for invalid track format in transport mode. Also remove the check for file protected since this is not a valid ESE handling case.

An issue was discovered in Insyde InsydeH2O with kernel 5.0 through 5.5. A stack buffer overflow leads to arbitrary code execution in the SetupUtility driver on Intel platforms. An attacker can change the values of certain UEFI variables. If the size of the second variable exceeds the size of the first, then the buffer will be overwritten. This issue affects the SetupUtility driver of InsydeH2O.

Root cause appears that when GPU metrics tables for v2_4 parts were added it was not considered to enlarge the table to fit. The fix in this patch is rather "brute force" and perhaps later should be done in a smarter way, by extracting and consolidating the part version to size logic to a common helper, instead of brute forcing the largest possible allocation. Nevertheless, for now this works and fixes the out of bounds write. v2: * Drop impossible v3_0 case. (Mario) (cherry picked from commit 0880f58f9609f0200483a49429af0f050d281703)

Memory corruption while sound model registration for voice activation with audio kernel driver.

H3C Magic NX18 Plus NX18PV100R003 was discovered to contain a stack overflow via the function edditactionlist.

An out-of-bounds memory write flaw was found in the Linux kernel’s Kid-friendly Wired Controller driver. This flaw allows a local user to crash or potentially escalate their privileges on the system. It is in bigben_probe of drivers/hid/hid-bigbenff.c. The reason is incorrect assumption - bigben devices all have inputs. However, malicious devices can break this assumption, leaking to out-of-bound write.

TOTOLINK A3700R V9.1.2u.6134_B20201202 was discovered to contain a stack overflow via the pppoeUser parameter.

In the Linux kernel, the following vulnerability has been resolved: vduse: fix memory corruption in vduse_dev_ioctl() The "config.offset" comes from the user. There needs to a check to prevent it being out of bounds. The "config.offset" and "dev->config_size" variables are both type u32. So if the offset if out of bounds then the "dev->config_size - config.offset" subtraction results in a very high u32 value. The out of bounds offset can result in memory corruption.
