CVE-2026-80587 mptcp: avoid combining some incoming suboptions

In the Linux kernel, the following vulnerability has been resolved: mptcp: avoid combining some incoming suboptions Some MPTCP suboptions are mutually exclusive according to the RFC8684, but also because in different places, the code doesn't expect some combinations to be present. That's speciall...

CVE-2026-80587

CVE-2026-80587 affects the Linux kernel MPTCP subsystem . The vulnerability arises because the kernel failed to enforce mutual-exclusion rules on incoming MPTCP suboptions, while the same restrictions were already applied on the outgoing side via mptcp_write_options. Per RFC 8684, certain subopti...

CVE-2026-80571

CVE-2026-80571 affects the Linux kernel on powerpc/pseries systems, specifically the papr-phy-attest driver. In the function papr_phy_attest_create_handle() , the field params->cmd.length is not validated before use, which can result in a buffer overflow . The driver also fails to free params ...

CVE-2026-80571 powerpc/pseries: papr-phy-attest - validate cmd.length, plug mem leak

In the Linux kernel, the following vulnerability has been resolved: powerpc/pseries: papr-phy-attest - validate cmd.length, plug mem leak In paprphyattestcreatehandle, the params-cmd.length is not validated before use, which can result in a buffer overlow. Check it and return -EINVAL if it is...

CVE-2026-80566 Input: hynitron_cstxxx - validate touch count and finger IDs

In the Linux kernel, the following vulnerability has been resolved: Input: hynitroncstxxx - validate touch count and finger IDs The driver allocates maxtouchnum input slots, which are indexed from zero through maxtouchnum - 1. The current check allows a finger ID equal to maxtouchnum to reach...

CVE-2026-80546 s390/zcrypt: Improve CCA CPRB length and overflow checks

In the Linux kernel, the following vulnerability has been resolved: s390/zcrypt: Improve CCA CPRB length and overflow checks The xcrbmsgtotype6cprbmsgx function lacks proper input validation, creating security vulnerabilities: 1. Integer overflow after CEIL4 alignment: Signed int variables could...

CVE-2026-80546

CVE-2026-80546 affects the s390/zcrypt subsystem of the Linux kernel, specifically the xcrb_msg_to_type6cprb_msgx() function. Three related input-validation flaws allow a local attacker with low privileges to trigger: (1) integer overflow during CEIL4 alignment, leading to undersized buffer alloc...
