In the Linux kernel, the following vulnerability has been resolved: of: reservedmem: prevent OOB when too many dynamic regions are defined On boot, fdtscanreservedmem saves each dynamically-placed /reserved-memory subnode into a local array of size MAXRESERVEDREGIONS. If the device tree defines...

CVE-2026-80672

CVE-2026-80672 is a u16 truncation in the Linux kernel's in-kernel NTFS driver, specifically in ntfs_check_restart_area(). The variable ra_len is declared as u16, but the computed length of the $LogFile log client record array can exceed 65535 (e.g., log_clients of 410 yields 65600), causing trun...

A network attacker who can reach th...

CVE-2026-59276

Several components in Spring Security compare security-sensitive values using standard string equality String.equals rather than a constant-time comparison. Because String.equals returns as soon as it finds a differing character, the time taken to reject an incorrect value is proportional to the...

GHSA-8X48-8G7J-RQXP Duplicate Advisory: Quadratic-time DoS in PorterStemmer via long runs of 'y'

Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-ww6m-cw3f-q94g. This link is maintained to preserve external references. Original Description nltk PorterStemmer in versions = 3.10.2 fixed in 3.10.3 contains an inefficient-algorithmic-complexity denial of...

CVE-2026-59276 Timing Attack via Non-Constant-Time Comparison of Sensitive Values

Several components in Spring Security compare security-sensitive values using standard string equality String.equals rather than a constant-time comparison. Because String.equals returns as soon as it finds a differing character, the time taken to reject an incorrect value is proportional to the...

CVE-2026-59276

Spring Security is affected by a timing attack vulnerability in several components that compare security-sensitive values using standard String.equals() instead of a constant-time comparison. Because String.equals() returns as soon as a differing character is found, the response time for rejectin...

CVE-2026-81722 nltk PorterStemmer before 3.10.3 Quadratic-time DoS

nltk PorterStemmer in versions = 3.10.2 fixed in 3.10.3 contains an inefficient-algorithmic-complexity denial of service in PorterStemmer.stem. The isconsonant helper walks backward over the entire run of trailing 'y' characters on every call, and measure invokes it for each stem position, causin...

CVE-2026-81722

nltk PorterStemmer in versions ≤ 3.10.2 is vulnerable to an inefficient-algorithmic-complexity denial of service in PorterStemmer.stem(). The root cause is that the _is_consonant() helper walks backward over the entire run of trailing 'y' characters on every call, and _measure() invokes it for ea...
