| 2024-05-19 | CVE-2024-35874 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: aio: Fix null ptr deref in aio_complete() wakeup list_del_init_careful() needs to be the last access to the wait queue entry - it effectively unlocks access. Previously, finish_wait() would see the empty list head and skip taking the lock, and then we'd return - but the completion path would still attempt to do the wakeup after the task_struct pointer had been overwritten. | 5.5 |
| 2024-05-19 | CVE-2024-35882 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: SUNRPC: Fix a slow server-side memory leak with RPC-over-TCP Jan Schunk reports that his small NFS servers suffer from memory exhaustion after just a few days. | 5.5 |
| 2024-05-19 | CVE-2024-35883 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: spi: mchp-pci1xxx: Fix a possible null pointer dereference in pci1xxx_spi_probe In function pci1xxxx_spi_probe, there is a potential null pointer that may be caused by a failed memory allocation by the function devm_kzalloc. Hence, a null pointer check needs to be added to prevent null pointer dereferencing later in the code. To fix this issue, spi_bus->spi_int[iter] should be checked. | 5.5 |
| 2024-05-19 | CVE-2024-35885 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: mlxbf_gige: stop interface during shutdown The mlxbf_gige driver intermittantly encounters a NULL pointer exception while the system is shutting down via "reboot" command. The mlxbf_driver will experience an exception right after executing its shutdown() method. | 5.5 |
| 2024-05-19 | CVE-2024-35889 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: idpf: fix kernel panic on unknown packet types In the very rare case where a packet type is unknown to the driver, idpf_rx_process_skb_fields would return early without calling eth_type_trans to set the skb protocol / the network layer handler. This is especially problematic if tcpdump is running when such a packet is received, i.e. | 5.5 |
| 2024-05-19 | CVE-2024-35891 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net: phy: micrel: Fix potential null pointer dereference In lan8814_get_sig_rx() and lan8814_get_sig_tx() ptp_parse_header() may return NULL as ptp_header due to abnormal packet type or corrupted packet. Fix this bug by adding ptp_header check. Found by Linux Verification Center (linuxtesting.org) with SVACE. | 5.5 |
| 2024-05-19 | CVE-2024-35895 | Improper Locking vulnerability in multiple products In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: Prevent lock inversion deadlock in map delete elem syzkaller started using corpuses where a BPF tracing program deletes elements from a sockmap/sockhash map. | 5.5 |
| 2024-05-19 | CVE-2024-35902 | NULL Pointer Dereference vulnerability in multiple products In the Linux kernel, the following vulnerability has been resolved: net/rds: fix possible cp null dereference cp might be null, calling cp->cp_conn would produce null dereference [Simon Horman adds:] Analysis: * cp is a parameter of __rds_rdma_map and is not reassigned. * The following call-sites pass a NULL cp argument to __rds_rdma_map() - rds_get_mr() - rds_get_mr_for_dest * Prior to the code above, the following assumes that cp may be NULL (which is indicative, but could itself be unnecessary) trans_private = rs->rs_transport->get_mr( sg, nents, rs, &mr->r_key, cp ? cp->cp_conn : NULL, args->vec.addr, args->vec.bytes, need_odp ? ODP_ZEROBASED : ODP_NOT_NEEDED); * The code modified by this patch is guarded by IS_ERR(trans_private), where trans_private is assigned as per the previous point in this analysis. The only implementation of get_mr that I could locate is rds_ib_get_mr() which can return an ERR_PTR if the conn (4th) argument is NULL. * ret is set to PTR_ERR(trans_private). rds_ib_get_mr can return ERR_PTR(-ENODEV) if the conn (4th) argument is NULL. Thus ret may be -ENODEV in which case the code in question will execute. Conclusion: * cp may be NULL at the point where this patch adds a check; this patch does seem to address a possible bug | 5.5 |
| 2024-05-19 | CVE-2024-35904 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: selinux: avoid dereference of garbage after mount failure In case kern_mount() fails and returns an error pointer return in the error branch instead of continuing and dereferencing the error pointer. While on it drop the never read static variable selinuxfs_mount. | 5.5 |
| 2024-05-19 | CVE-2024-35907 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: mlxbf_gige: call request_irq() after NAPI initialized The mlxbf_gige driver encounters a NULL pointer exception in mlxbf_gige_open() when kdump is enabled. | 5.5 |
