Fix it by treating ICE_VSI_LB VSIs slightly more like normal PF VSIs and letting them have a q_vector. It's just a dummy, because the loopback test does not use interrupts, but it contains a napi struct that can be passed to libeth_rx_fq_create() called from ice_vsi_cfg_rxq() -> ice_rxq_pp_create(). | ||||
| CVE-2026-23358 | 1 Linux | 1 Linux Kernel | 2026-03-27 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Fix error handling in slot reset If the device has not recovered after slot reset is called, it goes to out label for error handling. There it could make decision based on uninitialized hive pointer and could result in accessing an uninitialized list. Initialize the list and hive properly so that it handles the error situation and also releases the reset domain lock which is acquired during error_detected callback.

| CVE-2026-23367 | 1 Linux | 1 Linux Kernel | 2026-03-27 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: wifi: radiotap: reject radiotap with unknown bits The radiotap parser is currently only used with the radiotap namespace (not with vendor namespaces), but if the undefined field 18 is used, the alignment/size is unknown as well. In this case, iterator->_next_ns_data isn't initialized (it's only set for skipping vendor namespaces), and syzbot points out that we later compare against this uninitialized value. Fix this by moving the rejection of unknown radiotap fields down to after the in-namespace lookup, so it will really use iterator->_next_ns_data only for vendor namespaces, even in case undefined fields are present. | ||||
| CVE-2026-23381 | 1 Linux | 1 Linux Kernel | 2026-03-27 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: net: bridge: fix nd_tbl NULL dereference when IPv6 is disabled When booting with the 'ipv6.disable=1' parameter, the nd_tbl is never initialized because inet6_init() exits before ndisc_init() is called which initializes it. Then, if neigh_suppress is enabled and an ICMPv6 Neighbor Discovery packet reaches the bridge, br_do_suppress_nd() will dereference ipv6_stub->nd_tbl which is NULL, passing it to neigh_lookup(). This causes a kernel NULL pointer dereference. BUG: kernel NULL pointer dereference, address: 0000000000000268 Oops: 0000 [#1] PREEMPT SMP NOPTI [...] RIP: 0010:neigh_lookup+0x16/0xe0 [...] Call Trace: <IRQ> ? neigh_lookup+0x16/0xe0 br_do_suppress_nd+0x160/0x290 [bridge] br_handle_frame_finish+0x500/0x620 [bridge] br_handle_frame+0x353/0x440 [bridge] __netif_receive_skb_core.constprop.0+0x298/0x1110 __netif_receive_skb_one_core+0x3d/0xa0 process_backlog+0xa0/0x140 __napi_poll+0x2c/0x170 net_rx_action+0x2c4/0x3a0 handle_softirqs+0xd0/0x270 do_softirq+0x3f/0x60 Fix this by replacing IS_ENABLED(IPV6) call with ipv6_mod_enabled() in the callers. This is in essence disabling NS/NA suppression when IPv6 is disabled. | ||||
| CVE-2026-2100 | 1 Redhat | 2 Enterprise Linux, Openshift | 2026-03-26 | 5.3 Medium |
| A flaw was found in p11-kit. A remote attacker could exploit this vulnerability by calling the C_DeriveKey function on a remote token with specific IBM kyber or IBM btc derive mechanism parameters set to NULL. This could lead to the RPC-client attempting to return an uninitialized value, potentially resulting in a NULL dereference or undefined behavior. This issue may cause an application level denial of service or other unpredictable system states. | ||||
| CVE-2026-23282 | 1 Linux | 1 Linux Kernel | 2026-03-26 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: smb: client: fix oops due to uninitialised var in smb2_unlink() If SMB2_open_init() or SMB2_close_init() fails (e.g. reconnect), the iovs set @rqst will be left uninitialised, hence calling SMB2_open_free(), SMB2_close_free() or smb2_set_related() on them will oops. Fix this by initialising @close_iov and @open_iov before setting them in @rqst. | ||||
| CVE-2026-23293 | 1 Linux | 1 Linux Kernel | 2026-03-26 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: net: vxlan: fix nd_tbl NULL dereference when IPv6 is disabled When booting with the 'ipv6.disable=1' parameter, the nd_tbl is never initialized because inet6_init() exits before ndisc_init() is called which initializes it. If an IPv6 packet is injected into the interface, route_shortcircuit() is called and a NULL pointer dereference happens on neigh_lookup(). BUG: kernel NULL pointer dereference, address: 0000000000000380 Oops: Oops: 0000 [#1] SMP NOPTI [...] RIP: 0010:neigh_lookup+0x20/0x270 [...] Call Trace: <TASK> vxlan_xmit+0x638/0x1ef0 [vxlan] dev_hard_start_xmit+0x9e/0x2e0 __dev_queue_xmit+0xbee/0x14e0 packet_sendmsg+0x116f/0x1930 __sys_sendto+0x1f5/0x200 __x64_sys_sendto+0x24/0x30 do_syscall_64+0x12f/0x1590 entry_SYSCALL_64_after_hwframe+0x76/0x7e Fix this by adding an early check on route_shortcircuit() when protocol is ETH_P_IPV6. Note that ipv6_mod_enabled() cannot be used here because VXLAN can be built-in even when IPv6 is built as a module. | ||||
| CVE-2026-4715 | 1 Mozilla | 2 Firefox, Firefox Esr | 2026-03-26 | 9.1 Critical |
| Uninitialized memory in the Graphics: Canvas2D component. This vulnerability affects Firefox < 149, Firefox ESR < 140.9, Thunderbird < 149, and Thunderbird < 140.9. | ||||
| CVE-2026-4716 | 1 Mozilla | 2 Firefox, Firefox Esr | 2026-03-26 | 9.1 Critical |
| Incorrect boundary conditions, uninitialized memory in the JavaScript Engine component. This vulnerability affects Firefox < 149, Firefox ESR < 140.9, Thunderbird < 149, and Thunderbird < 140.9. | ||||
| CVE-2026-23366 | 1 Linux | 1 Linux Kernel | 2026-03-26 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: drm/client: Do not destroy NULL modes 'modes' in drm_client_modeset_probe may fail to kcalloc. If this occurs, we jump to 'out', calling modes_destroy on it, which dereferences it. This may result in a NULL pointer dereference in the error case. Prevent that. | ||||
| CVE-2026-3497 | 1 Ubuntu | 1 Openssh | 2026-03-23 | 8.2 High |
| Vulnerability in the OpenSSH GSSAPI delta included in various Linux distributions. This vulnerability affects the GSSAPI patches added by various Linux distributions and does not affect the OpenSSH upstream project itself. The usage of sshpkt_disconnect() on an error, which does not terminate the process, allows an attacker to send an unexpected GSSAPI message type during the GSSAPI key exchange to the server, which will call the underlying function and continue the execution of the program without setting the related connection variables. As the variables are not initialized to NULL the code later accesses those uninitialized variables, accessing random memory, which could lead to undefined behavior. The recommended workaround is to use ssh_packet_disconnect() instead, which does terminate the process. The impact of the vulnerability depends heavily on the compiler flag hardening configuration. | ||||
| CVE-2025-69651 | 1 Gnu | 1 Binutils | 2026-03-19 | 5.5 Medium |
| GNU Binutils thru 2.46 readelf contains a vulnerability that leads to an invalid pointer free when processing a crafted ELF binary with malformed relocation or symbol data. If dump_relocations returns early due to parsing errors, the internal all_relocations array may remain partially uninitialized. Later, process_got_section_contents() may attempt to free an invalid r_symbol pointer, triggering memory corruption checks in glibc and causing the program to terminate with SIGABRT. No evidence of further memory corruption or code execution was observed; the impact is limited to denial of service. NOTE: this is disputed by third parties because the observed behavior occurred only in pre-release code and did not affect any tagged version. | ||||
| CVE-2026-28691 | 1 Imagemagick | 1 Imagemagick | 2026-03-11 | 7.5 High |
| ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16 and 6.9.13-41, an uninitialized pointer dereference vulnerability exists in the JBIG decoder due to a missing check. This vulnerability is fixed in 7.1.2-16 and 6.9.13-41. | ||||
| CVE-2026-28547 | 1 Huawei | 1 Harmonyos | 2026-03-06 | 6.8 Medium |
| Vulnerability of uninitialized pointer access in the scanning module. Impact: Successful exploitation of this vulnerability may affect availability. | ||||
| CVE-2026-2805 | 1 Mozilla | 2 Firefox, Thunderbird | 2026-03-06 | 9.8 Critical |
| Invalid pointer in the DOM: Core & HTML component. This vulnerability affects Firefox < 148 and Thunderbird < 148. | ||||
| CVE-2026-2785 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2026-03-06 | 8.8 High |
| Invalid pointer in the JavaScript Engine component. This vulnerability affects Firefox < 148, Firefox ESR < 140.8, Thunderbird < 148, and Thunderbird < 140.8. | ||||
