Jan 2026: Capability Access Management Service (camsvc) Information Disclosure Vulnerability
CVE-2026-20835 Published on January 13, 2026
Capability Access Management Service (camsvc) Information Disclosure Vulnerability
Out-of-bounds read in Capability Access Management Service (camsvc) allows an authorized attacker to disclose information locally.
Weakness Type
Out-of-bounds Read
The software reads data past the end, or before the beginning, of the intended buffer. Typically, this can allow attackers to read sensitive information from other memory locations or cause a crash. A crash can occur when the code reads a variable amount of data and assumes that a sentinel exists to stop the read operation, such as a NUL in a string. The expected sentinel might not be located in the out-of-bounds memory, causing excessive data to be read, leading to a segmentation fault or a buffer overflow. The software may modify an index or perform pointer arithmetic that references a memory location that is outside of the boundaries of the buffer. A subsequent read operation then produces undefined or unexpected results.
