Denial of Service (DoS)

Overview Affected versions of this package are vulnerable to Denial of Service DoS via the groupcomments function in sqlparse/engine/grouping.py when parsing a statement composed entirely of comment tokens e.g., repeated -- c\n lines. The function rescans the entire remaining token tail once per...

CVE-2026-72082

A flaw was found in the Linux kernel's SCSI Small Computer System Interface elx: efct module. This vulnerability occurs when an I/O abort operation fails to properly release a resource reference. This can lead to a permanent resource leak, which prevents subsequent attempts to abort the same I/O...

Regular Expression Denial of Service (ReDoS)

Overview Affected versions of this package are vulnerable to Regular Expression Denial of Service ReDoS via the lexer's handling of dollar-quoted literals and multiline comments. The regular expressions used to match $tag$...$tag$ dollar-quoted literals and /.../ multiline comments employed a laz...

GHSA-PWGV-4X5Q-6M9F sqlparse: TokenList.__init__ materializes O(subtree) value per group, causing CPU DoS before depth/token caps trigger

Summary sqlparse ships hard limits MAXGROUPINGDEPTH=100, MAXGROUPINGTOKENS=10000 intended to bound parsing work on attacker-supplied SQL, but the path that reaches those limits is itself Ondepth per token-group construction. A 1-2 KB SQL payload e.g. SELECT 1 ... with 500-2000 nesting levels, or ...

sqlparse: Quadratic O(n²) DoS in group_comments

Summary A comment-only statement -- c\nn may cause a Denial of Service DoS. Details Location: sqlparse/engine/grouping.py:331-341 groupcomments, invoked first in group at grouping.py:439. Reachable via sqlparse.parse and sqlparse.formatsql, stripcomments=True. A statement made of many single-line...

CVE-2026-72163

A flaw was found in the Linux kernel's OCFS2 component. A local user with write access to an OCFS2 filesystem could trigger a kernel panic by performing a direct write over unwritten extents. This occurs when the journal aborts during Direct I/O DIO completion, leading to a NULL pointer dereferen...

BIT-PYTHON-2026-6879 Quadratic Behavior in xml.etree.ElementPath Index Predicates

Element.findall and fully-consumed Element.iterfind exhibit On^2 time complexity when using XPath index predicates e.g. 1, last, last-N on XML documents with many same-tag siblings. Element.find is only affected when the first match is near the end of the sibling list, such as with last or...
