https://notcve.org/view.php?id=CVE-2024-42131
In the Linux kernel, the following vulnerability has been resolved: mm: avoid overflows in dirty throttling logic The dirty throttling logic is interspersed with assumptions that dirty limits in PAGE_SIZE units fit into 32-bit (so that various multiplications fit into 64-bits). If limits end up being larger, we will hit overflows, possible divisions by 0 etc. Fix these problems by never allowing so large dirty limits as they have dubious practical value anyway. For dirty_bytes / dirty_background_bytes interfaces we can just refuse to set so large limits. For dirty_ratio / dirty_background_ratio it isn't so simple as the dirty limit is computed from the amount of available memory which can change due to memory hotplug etc. • https://git.kernel.org/stable/c/2b2d2b8766db028bd827af34075f221ae9e9efff https://git.kernel.org/stable/c/4d3817b64eda07491bdd86a234629fe0764fb42a https://git.kernel.org/stable/c/7a49389771ae7666f4dc3426e2a4594bf23ae290 https://git.kernel.org/stable/c/a25e8536184516b55ef89ab91dd2eea429de28d2 https://git.kernel.org/stable/c/c83ed422c24f0d4b264f89291d4fabe285f80dbc https://git.kernel.org/stable/c/bd16a7ee339aef3ee4c90cb23902afb6af379ea0 https://git.kernel.org/stable/c/8e0b5e7f2895eccef5c2a0018b589266f90c4805 https://git.kernel.org/stable/c/385d838df280eba6c8680f9777bfa0d0b • CWE-190: Integer Overflow or Wraparound •

In the Linux kernel, the following vulnerability has been resolved: nfc/nci: Add the inconsistency check between the input data length and count write$nci(r0, &(0x7f0000000740)=ANY=[@ANYBLOB="610501"], 0xf) Syzbot constructed a write() call with a data length of 3 bytes but a count value of 15, which passed too little data to meet the basic requirements of the function nci_rf_intf_activated_ntf_packet(). Therefore, increasing the comparison between data length and count value to avoid problems caused by inconsistent data length and count. • https://git.kernel.org/stable/c/f07bcd8bba803c9e6ad2048543185d6c56587a2f https://git.kernel.org/stable/c/41f5e2840cd0629f049ce5ce2f8dd10a8299de42 https://git.kernel.org/stable/c/056478b4321b36ca33567089d39ac992f6c9c37a https://git.kernel.org/stable/c/22a72c1c10f43ca645a98725e0faff34592f4d08 https://git.kernel.org/stable/c/068648aab72c9ba7b0597354ef4d81ffaac7b979 •

CVSS: -EPSS: 0%CPEs: 7EXPL: 0CVE-2024-42127 – drm/lima: fix shared irq handling on driver remove
https://notcve.org/view.php?id=CVE-2024-42127
In the Linux kernel, the following vulnerability has been resolved: drm/lima: fix shared irq handling on driver remove lima uses a shared interrupt, so the interrupt handlers must be prepared to be called at any time. At driver removal time, the clocks are disabled early and the interrupts stay registered until the very end of the remove process due to the devm usage. This is potentially a bug as the interrupts access device registers which assumes clocks are enabled. A crash can be triggered by removing the driver in a kernel with CONFIG_DEBUG_SHIRQ enabled. This patch frees the interrupts at each lima device finishing callback so that the handlers are already unregistered by the time we fully disable clocks. • https://git.kernel.org/stable/c/0d60c43df59ef01c08dc7b0c45495178f9d05a13 https://git.kernel.org/stable/c/25d0d9b83d855cbc5d5aa5ae3cd79d55ea0c84a8 https://git.kernel.org/stable/c/17fe8b75aaf0bb1bdc31368963446b421c22d0af https://git.kernel.org/stable/c/0a487e977cb8897ae4c51ecd34bbaa2b005266c9 https://git.kernel.org/stable/c/04d531b9a1875846d4f89953b469ad463aa7a770 https://git.kernel.org/stable/c/b5daf9217a50636a969bc1965f827878aeb09ffe https://git.kernel.org/stable/c/a6683c690bbfd1f371510cb051e8fa49507f3f5e •
