kernel: scsi: qla2xxx: Bound rsp_info_len to avoid OOB sense-data read

A flaw was found in the Linux kernel's scsi: qla2xxx driver. A remote attacker, by sending a specially crafted Fibre Channel Protocol FCP response, could cause an integer underflow. This underflow leads to an out-of-bounds read when handling sense data, potentially disclosing sensitive memory...

kernel: mac802154: llsec: add skb_cow_data() before in-place crypto

A flaw was found in the Linux kernel's mac802154 IEEE 802.15.4 MAC security component. This vulnerability allows for data corruption and potential kernel crashes when cryptographic transformations are performed on shared network packet data without proper isolation. A remote attacker could exploi...

kernel: sctp: don't free the ASCONF's own transport in DEL-IP processing

A flaw was found in the Stream Control Transmission Protocol SCTP implementation within the Linux kernel. A remote attacker could send a specially crafted sequence of ASCONF Add IP Address Configuration chunks, including DEL-IP Delete IP Address parameters, to trigger a use-after-free condition...

kernel: netfilter: nf_conntrack_sip: widen NAT rewrite delta to s32 in sip_help_tcp()

A flaw was found in the Linux kernel's netfilter Session Initiation Protocol SIP connection tracking module nfconntracksip. A remote attacker could send specially crafted SIP messages that cause an integer overflow during Network Address Translation NAT rewrite delta calculations. This overflow...

kernel: net: tun: bound receive headroom

A flaw was found in the Linux kernel's TUN/TAP driver. An integer underflow vulnerability exists in the tungetuser function when processing oversized headroom requests. This can occur if Open vSwitch OVS propagates an excessively large headroom request to the TUN or TAP device. Successful...

kernel: selinux: check connect-related permissions on TCP Fast Open

A flaw was found in the Linux kernel's Security-Enhanced Linux SELinux module. When using TCP Fast Open, SELinux failed to properly check connect-related permissions. This oversight could allow a local attacker to bypass SELinux network access controls, potentially enabling unauthorized network...

kernel: nvme-tcp: reject a read that transferred too few bytes

A flaw was found in the NVMe-TCP implementation of the Linux kernel. This vulnerability occurs when the system completes a data read request even if the connected controller transfers fewer bytes than expected. As a result, the user application receives a mix of legitimate and stale data,...

kernel: pppoe: reload header pointer after dev_hard_header()

A flaw was found in the Linux kernel's PPPoE Point-to-Point Protocol over Ethernet implementation. This vulnerability occurs because a pointer to network packet data is not updated after memory is reallocated, leading to the use of an outdated memory address. An attacker with local access could...

kernel: drm/amdgpu: Fix fence put before wait in amdgpu_amdkfd_submit_ib

A flaw was found in the Linux kernel's AMD GPU amdgpu driver. An issue in the amdgpuamdkfdsubmitib function allows a local user to trigger a use-after-free vulnerability. This occurs because a fence reference is incorrectly released before waiting for job completion, potentially freeing the memor...

kernel: ipvs: do not propagate one-packet flag to synced conns

A flaw was found in the Linux kernel's IP Virtual Server IPVS component. When a synced connection is established, it can incorrectly inherit a "one-packet" flag from its destination. This misconfiguration causes the connection's expiry process to mishandle its cleanup, leaving behind stale memory...

kernel: netfilter: nf_queue: hold bridge skb->dev while queued

A flaw was found in the Linux kernel's netfilter component. This vulnerability occurs because a queued bridge packet can retain a freed bridge master in its skb-dev field until it is reinjected. When the packet is later reinjected, the system attempts to use the freed bridge master, leading to a...

kernel: netfilter: ebtables SNAT target writes to shared memory pages during ARP hardware address rewrite

A flaw was found in the Linux kernel's netfilter bridge ebtables SNAT Source Network Address Translation module. This vulnerability allows a local attacker on a system configured with specific bridge netfilter rules to improperly modify underlying memory pages during an ARP Address Resolution...

freeipa: ipa: FreeIPA: trust-fetch-domains uses trust-read ACI to gate a privileged AD trust refresh, allowing unauthorized LDAP writes

A flaw was found in FreeIPA. The trust-fetch-domains command is gated by a read-only permission on the trust object rather than a trust-administration permission, allowing an authenticated, non-privileged IPA user to trigger a privileged Active Directory trust refresh using an attacker-supplied...

ipa: freeipa: FreeIPA: unauthenticated LDAP client can obtain administrator credentials via the self-managed-token ACI

A flaw was found in FreeIPA. The self-managed OTP token ACI does not require authentication and does not restrict which attributes may be added alongside the token entry. An unauthenticated LDAP client can exploit this, combined with a related flaw in the underlying directory server's ACI...

ipa: Privilege escalation via krbCanonicalName manipulation due to realm-unaware uniqueness enforcement in FreeIPA LDAP datastore

A privilege escalation flaw was found in FreeIPA. The uniqueness constraint enforced on Kerberos principal name attributes in the 389-ds directory server does not properly account for equivalent representations of the same principal name, allowing a user with sufficient LDAP write privileges to...

FreeIPA: idm: ipa: FreeIPA: Obtaining TGS with impersonating cname through trust relationships

A flaw was found in FreeIPA. When a trust relationship is configured between FreeIPA and Active Directory, Active Directory users can bypass authentication for FreeIPA services, including the portal, SMB server, and LDAP directory. This is possible by impersonating a client name in the Ticket...

ipa: FreeIPA: Unauthenticated DoS in `/ipa/i18n_messages` via Unbounded Request Body Read

A flaw was found in FreeIPA. A remote, unauthenticated attacker can exploit a vulnerability in the /ipa/i18nmessages endpoint by sending an arbitrarily large request body. This can cause the service to consume excessive memory, leading to memory exhaustion, degraded responsiveness, and a denial o...

freeIPA: idm: freeipa: idp-add eval() reachable before authorization check allows environment disclosure and denial of service

A flaw was found in FreeIPA's idp-add command, where insufficiently validated --organization/--base-url input reaches a constrained eval call before the corresponding LDAP access control check is enforced. This allows any authenticated IPA principal, regardless of privilege level, to enumerate an...

freeipa: ipa: FreeIPA/IdM: Cross-Site Scripting vulnerability allows arbitrary code execution via crafted URL

A flaw was found in FreeIPA. An unauthenticated remote attacker could exploit a DOM Cross-Site Scripting XSS vulnerability in the FreeIPA/IdM Web UI password reset page. By enticing a victim to click a specially crafted link and complete a password reset, the attacker could inject and execute...

ipa: FreeIPA: Unauthenticated DoS in `/ipa/migration/migration.py` via Unbounded Request Body Read

A flaw was found in FreeIPA. A remote, unauthenticated attacker can exploit this vulnerability by sending oversized form POST requests to the /ipa/migration/migration.py endpoint. This can force the migration handler to read attacker-controlled request bodies fully into memory, leading to increas...
