RHSA-2026:95264
Vulnerability from csaf_redhat - Published: 2026-11-04 16:18 - Updated: 2026-11-12 06:05A flaw was found in glibc (GNU C Library). A local attacker or application using the wordexp function with the WRDE_APPEND flag can trigger the interface to return invalid memory in the we_wordv member. This invalid memory, when subsequently processed by wordfree, may cause the process to abort, leading to a Denial of Service (DoS).

A flaw was found in glibc. When processing paths that start with a tilde (~) followed by a username, the `wordexp` function can be forced to allocate an excessive amount of memory on the program's stack. A remote attacker could exploit this by providing a very long username, leading to a stack exhaustion and causing a denial of service (DoS) for the affected application.
A flaw was found in the GNU C Library (glibc). This vulnerability could allow an attacker with local access to trigger a heap buffer overflow by manipulating how the `fopen` function handles certain input. This could lead to minor disruptions in system operations or limited access to sensitive information.
A flaw was found in glibc. An out-of-bounds array write vulnerability exists within the `tdelete` function. This issue occurs due to incorrect management of array sizes, which can lead to memory corruption. A local attacker with low privileges could potentially exploit this to cause a denial of service or disclose sensitive information.
A flaw was found in glibc. A remote attacker could exploit this vulnerability by providing specially crafted input during SHIFT_JISX0213 to UCS-4 text conversion. This crafted input can cause the application to repeatedly emit a buffered code point without consuming further input, leading to persistent retry churn. This can result in a denial of service (DoS) for callers converting untrusted text.
A flaw was found in glibc. Converting crafted EUC_JISX0213 input to UCS-4 or the internal wide character encoding (for example with iconv) can cause the converter to make no progress, hanging the calling application. Some EUC_JISX0213 sequences decode to two code points; if the output buffer has room for only the first, the second is stored in conversion state and returned as E2BIG, but that pending character is never cleared after it is emitted on the next call, so retries loop forever without consuming further input.
A flaw was found in OpenSSL. The Datagram Transport Layer Security (DTLS) retransmission mechanism fails to properly handle handshake message writes that are suspended before completion. A remote attacker could exploit this vulnerability during handshake message retransmission, causing OpenSSL to read past the message buffer or overwrite internal state required to resume writing. This issue can result in information disclosure through out-of-bounds memory reads or cause a Denial of Service (DoS) by crashing the process.
A flaw was found in PCRE2. An out-of-bounds write vulnerability exists in the `pcre2_dfa_match` function due to improper size checking when reusing cached workspace blocks. A remote attacker could exploit this by providing a specially crafted regular expression or a recursive pattern in conjunction with a small heap limit. This could lead to data corruption or potentially arbitrary code execution, compromising the integrity and availability of the system.
A flaw was found in PCRE2. On 32-bit platforms, an attacker can provide a specially crafted large pattern, leading to an out-of-bounds write within the pcre2_pattern_convert function. This vulnerability can result in high integrity impact, such as data corruption, and potentially a low availability impact, causing a denial of service.
A flaw was found in PCRE2. On 32-bit platforms, an integer overflow in the `pcre2_compile_32` function can lead to an out-of-bounds write. This vulnerability could allow a remote attacker to achieve a high integrity impact and a low availability impact, potentially leading to data corruption or denial of service.
A flaw was found in PCRE2, a library for processing regular expressions. The `pcre2_jit_match` function, which handles just-in-time (JIT) compilation for regular expressions, incorrectly manages memory when processing certain inputs. This memory corruption vulnerability could allow a local attacker to cause the application to crash, leading to a denial of service, or potentially execute unauthorized code.
A flaw was found in pcre2. When an application processes attacker-controlled regular expressions using certain Just-In-Time (JIT) compiler interfaces, an out-of-bounds write with arbitrary data can occur. An attacker could exploit this vulnerability to achieve arbitrary code execution, corrupt memory, or cause a denial of service (DoS).
The system certificate authority (CA) store in Red Hat products, distributed via ca-certificates RPM packages, included multiple root CA certificates of authorities, which signed intermediate CA certificates with weak private keys issued by the eMudhra certificate authority. A man-in-the-middle attacker could use this flaw to issue certificates for arbitrary host names signed by the weak intermediate CA certificates, which would be considered trusted by a TLS/SSL client using system CA store and cause such clients to connect to malicious sites. Due to inability to only distrust specific intermediate certificates in all clients using the system CA store, root CA certificates of authorities that signed weak intermediate CA certificates are being removed.

Some EUC_JISX0213 sequences decode to two code points; if the output buffer has room for only the first, the second is stored in conversion state and returned as E2BIG, but that pending character is never cleared after it is emitted on the next call, so retries loop forever without consuming further input.",

Nomenclature
- Seen: The vulnerability was mentioned, discussed, or observed by the user.
- Confirmed: The vulnerability has been validated from an analyst's perspective.
- Published Proof of Concept: A public proof of concept is available for this vulnerability.
- Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
- Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
- Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
- Not confirmed: The user expressed doubt about the validity of the vulnerability.
- Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.
Vulnerability timeline
Sightings and recorded dates, grouped by day · UTC
How durations are calculated
Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.
Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
