https://notcve.org/view.php?id=CVE-2024-49855
In the Linux kernel, the following vulnerability has been resolved: nbd: fix race between timeout and normal completion If request timetout is handled by nbd_requeue_cmd(), normal completion has to be stopped for avoiding to complete this requeued request, other use-after-free can be triggered. Fix the race by clearing NBD_CMD_INFLIGHT in nbd_requeue_cmd(), meantime make sure that cmd->lock is grabbed for clearing the flag and the requeue. • https://git.kernel.org/stable/c/2895f1831e911ca87d4efdf43e35eb72a0c7e66e https://git.kernel.org/stable/c/cdf62c535a9bfd5ff0eef4b91669da39d8abc0c3 https://git.kernel.org/stable/c/5171ef20bae852ff38f4cfdb368bcdcc744776d0 https://git.kernel.org/stable/c/9c25faf72d780a9c71081710cd48759d61ff6e9b https://git.kernel.org/stable/c/6e73b946a379a1dfbb62626af93843bdfb53753d https://git.kernel.org/stable/c/5236ada8ebbd9e7461f17477357582f5be4f46f7 https://git.kernel.org/stable/c/9a74c3e6c0d686c26ba2aab66d15ddb89dc139cc https://git.kernel.org/stable/c/c9ea57c91f03bcad415e1a20113bdb207 •

In the Linux kernel, the following vulnerability has been resolved: scsi: elx: libefc: Fix potential use after free in efc_nport_vport_del() The kref_put() function will call nport->release if the refcount drops to zero. The nport->release release function is _efc_nport_free() which frees "nport". But then we dereference "nport" on the next line which is a use after free. Re-order these lines to avoid the use after free. • https://git.kernel.org/stable/c/fcd427303eb90aa3cb08e7e0b68e0e67a6d47346 https://git.kernel.org/stable/c/16a570f07d870a285b0c0b0d1ca4dff79e8aa5ff https://git.kernel.org/stable/c/abc71e89170ed32ecf0a5a29f31aa711e143e941 https://git.kernel.org/stable/c/baeb8628ab7f4577740f00e439d3fdf7c876b0ff https://git.kernel.org/stable/c/7c2908985e4ae0ea1b526b3916de9e5351650908 https://git.kernel.org/stable/c/98752fcd076a8cbc978016eae7125b4971be1eec https://git.kernel.org/stable/c/2e4b02fad094976763af08fec2c620f4f8edd9ae •
CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-49851 – tpm: Clean up TPM space after command failure
https://notcve.org/view.php?id=CVE-2024-49851
In the Linux kernel, the following vulnerability has been resolved: tpm: Clean up TPM space after command failure tpm_dev_transmit prepares the TPM space before attempting command transmission. However if the command fails no rollback of this preparation is done. This can result in transient handles being leaked if the device is subsequently closed with no further commands performed. Fix this by flushing the space in the event of command transmission failure. • https://git.kernel.org/stable/c/745b361e989af21ad40811c2586b60229f870a68 https://git.kernel.org/stable/c/87e8134c18977b566f4ec248c8a147244da69402 https://git.kernel.org/stable/c/2c9b228938e9266a1065a3f4fe5c99b7235dc439 https://git.kernel.org/stable/c/ebc4e1f4492d114f9693950621b3ea42b2f82bec https://git.kernel.org/stable/c/c84ceb546f30432fccea4891163f7050f5bee5dd https://git.kernel.org/stable/c/82478cb8a23bd4f97935bbe60d64528c6d9918b4 https://git.kernel.org/stable/c/adf4ce162561222338cf2c9a2caa294527f7f721 https://git.kernel.org/stable/c/3f9f72d843c92fb6f4ff7460d774413cd •
CVSS: -EPSS: 0%CPEs: 5EXPL: 0CVE-2024-49850 – bpf: correctly handle malformed BPF_CORE_TYPE_ID_LOCAL relos
https://notcve.org/view.php?id=CVE-2024-49850
In the Linux kernel, the following vulnerability has been resolved: bpf: correctly handle malformed BPF_CORE_TYPE_ID_LOCAL relos In case of malformed relocation record of kind BPF_CORE_TYPE_ID_LOCAL referencing a non-existing BTF type, function bpf_core_calc_relo_insn would cause a null pointer deference. Fix this by adding a proper check upper in call stack, as malformed relocation records could be passed from user space. Simplest reproducer is a program: r0 = 0 exit With a single relocation record: .insn_off = 0, /* patch first instruction */ .type_id = 100500, /* this type id does not exist */ .access_str_off = 6, /* offset of string "0" */ .kind = BPF_CORE_TYPE_ID_LOCAL, See the link for original reproducer or next commit for a test case. • https://git.kernel.org/stable/c/74753e1462e77349525daf9eb60ea21ed92d3a97 https://git.kernel.org/stable/c/dc7ce14f00bcd50641f2110b7a32aa6552e0780f https://git.kernel.org/stable/c/2288b54b96dcb55bedebcef3572bb8821fc5e708 https://git.kernel.org/stable/c/584cd3ff792e1edbea20b2a7df55897159b0be3e https://git.kernel.org/stable/c/e7e9c5b2dda29067332df2a85b0141a92b41f218 https://git.kernel.org/stable/c/3d2786d65aaa954ebd3fcc033ada433e10da21c4 •
